Automatic close pull requests to reflection files

Even with the comment on top of the file people still send PRs changing inflectors. We can detect it and warn or even automatically close all PRs that touches this file.

Seems reasonable. We can probably have the automated message give 100% of the context needed.

Does this come up enough to bother? My recollection is that most of the inflection reports we see are issues, not PRs.

I see at least one per month. I thought that given we have a way to automatize the feedback we could use it, but we can keep doing it manually too.
