this won't be complained about so often.

For now, it only adds a link to the Discord server.

People sometimes use the bug report template for things that are support.
Maintainers will confirm whether it's a bug with the appropriate label.

We do this because the GitHub Actions behavior was changed recently
so as to not pass secrets to action runs started from forks, therefore
the API token passed cannot be used to change PR labels.

There may be an alternative in the future.

Provisional measure due to "Unexpected value 'if'" error. See https://github.community/t5/GitHub-API-Development-and/jobs-lt-job-id-gt-if-not-working/m-p/28980
