Upgrade to version 1.12.1.

Security issues fixed:

Other updates and bugfixes:

- Version 1.12.1:
* Bugfixes
- update to Beyla 2.7.10.

- Version 1.12.0:
* Breaking changes
- `prometheus.exporter.blackbox`, `prometheus.exporter.snmp` and `prometheus.exporter.statsd` now use the component ID instead of the hostname as their instance label in their exported metrics.
* Features
- (Experimental) Add an `otelcol.receiver.cloudflare` component to receive logs pushed by Cloudflare's LogPush jobs.
- (Experimental) Additions to experimental `database_observability.mysql` component:
- `explain_plans`
- collector now changes schema before returning the connection to the pool.
- collector now passes queries more permissively.
- enable `explain_plans` collector by default
- (Experimental) Additions to experimental `database_observability.postgres` component:
- `explain_plans`
- added the explain plan collector.
- collector now passes queries more permissively.
- `query_samples`
- add user field to wait events within `query_samples` collector.
- rework the query samples collector to buffer per-query execution state across scrapes and emit finalized entries.
- process turned idle rows to calculate finalization times precisely and emit first seen idle rows.
- `query_details`
- escape queries coming from `pg_stat_statements` with quotes.
- enable `explain_plans` collector by default.
- safely generate `server_id` when UDP socket used for database connection.
- add table registry and include 'validated' in parsed table name logs.
- Add `otelcol.exporter.googlecloudpubsub` community component to export metrics, traces, and logs to Google Cloud Pub/Sub topic.
- Add `structured_metadata_drop` stage for `loki.process` to filter structured metadata.
- Send remote config status to the remote server for the `remotecfg` service.
- Send effective config to the remote server for the `remotecfg` service.
- Add a `stat_statements` configuration block to the `prometheus.exporter.postgres` component to enable selecting both the query ID and the full SQL statement. The new block includes one option to enable statement selection, and another to configure the maximum length of the statement text.
- Add truncate stage for `loki.process` to truncate log entries, label values, and `structured_metadata` values.
- Add `u_probe_links` & `load_probe` configuration fields to alloy `pyroscope.ebpf` to extend configuration of the `opentelemetry-ebpf-profiler` to allow uprobe profiling and dynamic probing.
- Add `verbose_mode` configuration fields to `alloy pyroscope.ebpf` to be enable `ebpf-profiler` verbose mode.
- Add `file_match` block to `loki.source.file` for built-in file discovery using glob patterns.
- Add a regex argument to the `structured_metadata` stage in `loki.process` to extract labels matching a regular expression.
- OpenTelemetry Collector dependencies upgraded from v0.134.0 to v0.139.0.
- See the upstream [core](https://github.com/open-telemetry/opentelemetry-collector/blob/v0.139.0/CHANGELOG.md) and [contrib](https://github.com/open-telemetry/opentelemetry-collector- contrib/blob/v0.139.0/CHANGELOG.md) changelogs for more details.
- A new `mimir.alerts.kubernetes` component which discovers AlertmanagerConfig Kubernetes resources and loads them into a Mimir instance.
- Mark `stage.windowsevent` block in the `loki.process` component as GA.
* Enhancements
- Add per-application rate limiting with the strategy attribute in the `faro.receiver` component, to prevent one application from consuming the rate limit quota of others.

* Bugfixes
- Stop `loki.source.kubernetes` discarding log lines with duplicate timestamps.
- Fix direction of arrows for pyroscope components in UI graph.
- Only log EOF errors for syslog port investigations in `loki.source.syslog` as Debug, not Warn.
- Fix `prometheus.exporter.process` ignoring the `remove_empty_groups` argument.
- Fix issues with 'unknown series ref when trying to add exemplar' from `prometheus.remote_write` by allowing series ref links to be updated if they change.
- Fix `loki.source.podlogs` component to register the Kubernetes field index for `spec.nodeName` when node filtering is enabled, preventing 'Index with name `field:spec.nodeName` does not exist' errors.
- Fix issue in `loki.source.file` where scheduling files could take too long.
- Fix `loki.write` no longer includes internal labels __.
- Fix missing native histograms custom buckets (NHCB) samples from `prometheus.remote_write`.
