Update setuptools requirement from <=75.3.0 to <=75.6.0 in /.github/scripts

[dependabot]

Updates the requirements on setuptools to permit the latest version.

Changelog

Sourced from setuptools's changelog.

v75.6.0

Features

• Preserve original PKG-INFO into METADATA when creating wheel (instead of calling wheel.metadata.pkginfo_to_metadata). This helps to be more compliant with the flow specified in PEP 517. (#4701)
• Changed the WindowsSdkVersion, FrameworkVersion32 and FrameworkVersion64 properties of setuptools.msvc.PlatformInfo to return an empty tuple instead of None as a fallthrough case -- by :user:Avasam (#4754)

v75.5.0

Features

• Removed support for SETUPTOOLS_DANGEROUSLY_SKIP_PYPROJECT_VALIDATION, as it is deemed prone to errors. (#4746)

v75.4.0

Features

• Added support for the environment variable SETUPTOOLS_DANGEROUSLY_SKIP_PYPROJECT_VALIDATION=true, allowing users to bypass the validation of pyproject.toml. This option should be used only as a last resort when resolving dependency issues, as it may lead to improper functioning. Users who enable this setting are responsible for ensuring that pyproject.toml complies with setuptools requirements. (#4611)

  .. attention:: This environment variable was removed in a later version of setuptools.

• Require Python 3.9 or later. (#4718)

• Remove dependency on importlib_resources and the vendored copy of the library. Instead, setuptools consistently rely on stdlib's importlib.resources (available on Python 3.9+). (#4718)

• Setuptools' bdist_wheel implementation no longer produces wheels with the m SOABI flag (pymalloc-related). This flag was removed on Python 3.8+ (see :obj:sys.abiflags). (#4718)

• Updated vendored packaging version to 24.2. (#4740)
