chore: bump testfixtures from 10.0.0 to 11.0.0

[dependabot]

Bumps testfixtures from 10.0.0 to 11.0.0.

Changelog

Sourced from testfixtures's changelog.

11.0.0 (9 Mar 2026)

• Moved to a uv__-based, pyproject.toml-driven project layout, with main replacing master as the default git branch.

  __ https://docs.astral.sh/uv/

• Move from Circle CI to Github Actions for continuous integration and releasing.

• Lots of documentation has been refreshed.

• Python versions between 3.11 and 3.14, inclusive, are now supported.

• Python versions 3.10 and earlier are no longer supported.

• :class:TempDir is now introduced as a :class:~pathlib.Path-based alternative to :class:TempDirectory.

• :class:TempDir and :class:TempDirectory have grown support for dumping and parsing JSON, YAML and TOML natively by way of the :meth:~TempDir.dump and :meth:TempDir.parse methods.

• :class:TempDir and :class:TempDirectory now have :meth:~TempDir.read_text and :meth:TempDir.read_bytes methods that mirror the behaviour of their :class:~pathlib.Path equivalents.

• :class:TempDir and :class:TempDirectory now support :class:~pathlib.Path objects anywhere they previously supported string and sequences of strings.

• :class:TempDir and :class:TempDirectory now have a :meth:~TempDir.clone method for copying existing files or directories into themselves for using during testing.

• None can now be passed to :class:ShouldRaise to check that no exception is raised. This is useful for parameterised tests where some cases may expect an exception to be raised while others do not.

• :class:ShouldRaise now has a match parameter to bring feature parity with :func:pytest.raises.

• :class:Comparison now shows the wrong type when it is compared against a wrong type.

• :class:Comparison no longer spuriously reports :class:~testfixtures.comparison.AlreadySeen as the wrong type.

• Fixed a bug where comparing parameterised generic type objects resulted in an infinite loop.
