Idea: Auto-Set labels based on modified path

[silverwind]

From go-gitea/gitea#25667 (comment), I think it would be useful if the bot could auto-set some labels based on modified path. There are two kind of matching mechanisms needed:

1. If any path is modified. For example, every change in Makefile should get a build label.
2. If only a path is modified. For example a change only in docs should get a kind/docs label and maybe a skip-changelog, but a change that includes changes in docs and templates should not.

The config should be in the repo itself in .github/giteabot.yaml to be flexible to change:

autolabels:
  only:
    - globs: [docs/**]
      labels: [kind/docs, skip-changelog]
  any:
    - globs: [Makefile]
      labels: [build]

I think it makes more sense to have the file here

Multiple benefits of having bot config in-repo:

• Different config for different branches (may also be undesirable)
• Bot is usable on more than one repo

Something like this would be nice:

https://github.com/nodejs/node/blob/main/.github/label-pr-config.yml

Regex (with capture groups!) is the absolute flexibilty.

BTW, Here is the repo for that bot which is acually just a action in disguise:

https://github.com/nodejs/node-pr-labeler

Of course more generic actions for this exist, like https://github.com/actions/labeler, so I think we likely should not do it in this bot at all.

Agreed
