[FEATURE] Ability to create a Pull Request comment under different org/repo/pr_number

[Yethal]

I realize this might be an edge case but it'd be quite helpful if the action allowed submitting PR comments under custom owner/repo

What would be the use case here ?
In any case, the token would need to have access to the defined repo

For custom owner, not sure, I added it because it was easy to do so. For custom repo it'd allow users to pass feedback from workflows triggered by workflow_dispatch events back to the triggering PR. At my company we have workflows triggered over rest api via workflow_dispatch events that need to report their result to the calling PR but due to additional complexity we can't use regular workflow_call events.
