Subject: [PATCH 1/2] fix: exclude setuptools.tests from wheel distribution

The exclude patterns '*.tests' and '*.tests.*' match packages named
like 'foo.tests' but do not match 'setuptools/tests' because that
directory is a subpackage of setuptools, not a top-level package
matching the glob.

Add explicit 'setuptools.tests' and 'setuptools.tests.*' to the
exclude list so test files are not included in the wheel.

Fixes #5212

Subject: [PATCH 2/2] Revert redundant exclude patterns, add tests verifying
 glob patterns work

The existing exclude patterns `*.tests` and `*.tests.*` already correctly
exclude `setuptools.tests` and its subpackages via fnmatch glob matching.
The explicit `setuptools.tests` and `setuptools.tests.*` patterns were
redundant.

Add TestGlobExcludePatterns to verify the glob exclude patterns work as
expected, addressing the maintainer's review feedback.
