SCA: security update for projen (GHSA-gg2g-m5wc-vccq)

high Tenable Self-Hosted Container Security Plugin ID 415105

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - `projen` is a project generation tool that synthesizes project configuration files such as `package.json`,
 `tsconfig.json`, `.gitignore`, GitHub Workflows, `eslint`, `jest`, and more, from a well-typed definition
 written in JavaScript. Users of projen's `NodeProject` project type (including any project type derived
 from it) include a `.github/workflows/rebuild-bot.yml` workflow that may allow any GitHub user to trigger
 execution of un-trusted code in the context of the "main" repository (as opposed to that of a fork). In
 some situations, such untrusted code may potentially be able to commit to the "main" repository. The
 rebuild-bot workflow is triggered by comments including `@projen rebuild` on pull-request to trigger a re-
 build of the projen project, and updating the pull request with the updated files. This workflow is
 triggered by an `issue_comment` event, and thus always executes with a `GITHUB_TOKEN` belonging to the
 repository into which the pull-request is made (this is in contrast with workflows triggered by
 `pull_request` events, which always execute with a `GITHUB_TOKEN` belonging to the repository from which
 the pull-request is made). Repositories that do not have branch protection configured on their default
 branch (typically `main` or `master`) could possibly allow an untrusted user to gain access to secrets
 configured on the repository (such as NPM tokens, etc). Branch protection prohibits this escalation, as
 the managed `GITHUB_TOKEN` would not be able to modify the contents of a protected branch and affected
 workflows must be defined on the default branch. (CVE-2021-21423)
