🩹[Patch]: Fix repo linting on merge to main (#2)

This release updates the logic for determining pull request states in
the `scripts/main.ps1` script, making the conditions for open, updated,
abandoned, and merged pull requests more precise and adding improved
logging for GitHub event inputs.

- Fixes PSModule/Process-PSModule#256

**Improvements to PR state detection:**

* Refined the `$isOpenOrUpdatedPR` condition to trigger only for
`'opened'`, `'reopened'`, or `'synchronize'` actions, making it more
accurate than the previous logic.
* Updated the `$isMergedPR` condition to require both the `'closed'`
action and that the PR is marked as merged, preventing false positives.

**Logging enhancements:**

* Added output of relevant GitHub event environment variables at the
start of the job run conditions calculation for easier debugging and
traceability.
