thank you for adding this!

@asalzmann I'm not sure what the labeler check is, can you help me debug? Presumably because I haven't added a label, but also, I can't.

[asalzmann]

Ah, yeah this is an annoying bug. The labeler action scans the changes and adds labels accordingly (using a project secret with write permissions). However, it doesn't work if you're merging in from a fork! actions/labeler#12
