attr: vendor 22.1.0...

attr: vendor 22.1.0 The previous version was 5 years old, and pytype 2022.06.30 started complaining about various uses (e.g. seeing `mercurial.thirdparty.attr._make._CountingAttr` instead of `bytearray`). Hopefully this helps. Additionally, this has official python 3.11 support. The `attrs` package is left out, because it is simply a bunch of *.pyi stubs and `from attr.X import *`, and that's not how they've been used up to this point. We'd probably need to customize those anyway to `from mercurial.thirdparty.attr import *`.
