Upgrade PyYAML to version 6

Do we really want to specify an exact version? pip install 6.0.0 works, and looking at the changelog, bugfix releases will likely be numbered like 6.0.x.

[srittau]

Using 6.0.* won't work, because there is no matching version at the moment. We can update this, once 6.0.1 gets released.

[hauntsaninja]

The following seems to work just fine for me, pip install 'pyyaml==6.0.*'

[srittau]

That's weird. There were problems with using stars for non-existing parts in CI when doing the change to allowing star syntax. I'll try it here.

This introduces a bunch of new stubtest warnings, but they somehow don't occur in CI. Here's this PR, with pyyaml 6.0 (aka pyyaml 6.0.0, both seem to install the same thing):

It's because they're allowlisted: https://github.com/python/typeshed/blob/master/stubs/PyYAML/@tests/stubtest_allowlist.txt
(+ that we run in CI with --ignore-missing-stub)

allowlist dates back to the initial commit, which means they're allowlisted to have CI be green, rather than any especially good reason.

[srittau]

I'll have a look.

Thanks, skimmed, seems fine!
