Automated comments on PRs don't work

[asamalik]

Recently, @regexowl implemented a super helpful test that posts comments to PRs, checking for any potential errors in the configs.

This seemd to work great in all our tests, until someone else sent a PR and the test failed with the following error:

Unhandled error: HttpError: Resource not accessible by integration

It appears that this is a known limitation of GitHub Actions.

If anyone knows any way around this, please let me know!

We could use pull_request_target instead of pull_request which would "work", but there are security caveats.

Here's more info with a potential solution.
