Release 9.0.0

[github-actions]

Created by the prepare release pr workflow.

Once all builds pass and it has been approved by one or more maintainers, start the deploy workflow, using these parameters:

• Use workflow from: release-9.0.0.
• Release version: 9.0.0.

Or execute on the command line:

gh workflow run deploy.yml -r release-9.0.0 -f version=9.0.0

After the workflow has been approved by a core maintainer, the package will be uploaded to PyPI automatically.

I will edit the changes later, but any comments welcome in the meantime.

The RTD build has some error in subtests.rst:

The RTD build has some error in subtests.rst:

Seem related to the new u character that is used as short letter for a failed subtest:

uuuuuF                                                               [100%]

We might need to update the pytest highlighter, perhaps @asottile can help?

Otherwise we can change from .. code-block:: pytest to .. code-block:: console and lose the syntax highlighting.

[bluetech]

These should not be removed, need to investigate.

[bluetech]

This might be expected but I'm not sure, need to check.

[bluetech]

Something's gone wrong here, probably doesn't pick up the config due to the toml/ini change. Are the # content of comments actually directives? I removed some of them. Need to check it.

[nicoddemus]

Are the # content of comments actually directives?

They are directives to regendoc.

[bluetech]

This is an improvement I think. Though maybe we should just omit if None.

[bluetech]

Should not have disappeared.

[bluetech]

I addressed @nicoddemus's comments and edited the changelog.

The other parts of the diff have some problems I need to check.

[asottile]

I can take a look at the highlighter later today probably

[bluetech]

I tried to fix regendoc to handle nested directives but my simplistic attempt (fiddling with the dedent function) fails on the full pytest docs. regendoc works on the textual level and treats a consecutive sequence of lines with a non-zero indentation (modulo empty lines) to be a "block". That's doesn't handle nesting. Need to think of another approach.
