Post comment as feedback for /packit koji-tag

Fixes #2552
I did not include any specific details about the requested tagging, as the feedback should be quick and to stay consistent with other feedback comments.
I would link some interface where users could watch the activity, but not sure if there is anything like that (like a specific Koji subpage), @nforro do you have any suggestions?
