chore(ci): Add action to track all PRs as issues

[github-actions]

Note

The pull request "chore(ci): Add action to track all PRs as issues" was created by @andreiborza but did not reference an issue. Therefore this issue was created for better visibility in external tools like Linear.

This workflow checks PR descriptions (like this one) to see if it can find an associated GitHub or Linear issue ID. If nothing is found, the workflow will create a new GitHub Issue which will then be referenced in this PR. As all other GitHub issues, this newly created one will then be synced to Linear as well.

This will increase visibility of (community) PRs in external tools like Linear.
