fix: stop github reporter deleting other PR comments

[LukoJy3D]

We are running Pint alongside various other scripts/tools, such as promtool, mimirtool, and cortextool, since they all share the alerting pipelines for promql/logql. After 0.84.0 we noticed both user and other bot comments getting deleted.

level=INFO msg="Deleting stale general comment" reporter=GitHub id=5237764226
level=INFO msg="Deleting stale general comment" reporter=GitHub id=5237764454

We need to have some safeguards, so Pint detects its own comments.

Thanks, it's looks fine overall but I'll need to review it fully and maybe tweak a few things

@prymitive, would love to get this solved. We pinned an older version, but we're missing out on some great new stuff!

Regarding the logic itself, maybe it would make more sense to edit/enrich the same pint comment with additional info when different run results are produced, rather than deleting it.
