Remove or update existing PR comments when adding a new one

[gabrielfeo]

Given I set add-job-summary-as-pr-comment: 'on-failure',
And 'foo' job has failed leaving a PR comment with the failure
When a later run of 'foo' succeeds

Then should the failure comment be removed? From what I gathered, that's not implemented, so I'm opening a discussion about it. Repro of current behavior: gabrielfeo/develocity-api-kotlin#233

In my opinion, it'd be best to either remove the comment or update it with an OK sign and the latest (successful) build scan. When the job succeeds, the failure comment becomes outdated info.

You're right we don't do anything to remove or modify previous job summary comments when submitting a new one.
Likely the ideal default behaviour would be to replace any outdated PR comments with a simple link to the GitHub Actions build (removing the large summary). Although removing it would also be reasonable behaviour I guess.
