build(deps): bump setuptools from 68.1.2 to 68.2.1

[dependabot[bot]]

Bumps setuptools from 68.1.2 to 68.2.1.

Changelog

Sourced from setuptools's changelog.

v68.2.1

Bugfixes

• Avoid using caching attributes in Distribution.metadata for requirements. This is done for backwards compatibility with customizations that attempt to modify install_requires or extras_require at a late point (still not recommended). (#4043)

Misc

• #4045

v68.2.0

Features

• Rework how setuptools internally handles dependencies/install_requires and optional-dependencies/extras_require. (#3903)
• Improve the generated PKG-INFO files, by adding Requires-Dist fields. Previously, these fields would be omitted in favour of a non-standard *.egg-info/requires.txt file (which is still generated for the time being). (#3904)
• Improve atomicity when writing PKG-INFO files to avoid race conditions with importlib.metadata. (#3904)

Bugfixes

• Fix the name given to the *-nspkg.pth files in editable installs, ensuring they are unique per distribution. (#4041)
• Workaround some limitations on pkg_resources-style legacy namespaces in the meta path finder for editable installations. (#4041)

Misc

• #4023, #4027, #4027
