bincrafters-conventions: ability to skip bot

[Croydon]

sometimes it is just unwanted that the bot pushes convention updates, hence there should be a way to skip it

Possibilities:

• add a tag to PR title
• OR add a tag to PR description
• OR add a tag to the latest(?)/any(?) commit message
• OR detect if bots' commits got reverted (not sure how hard this is)

Also, maybe put a comment on the line you don't want the bot to modify ?

I don't like this idea as it would mean having to put tool specific meta data into recipes 🤔

Usually commit message is used for most CI services, but thinking about CCI, when I open a PR there and the bot updates, I would like something more straightforward, like the first option: add a tag to PR title.
