Raise min setuptools and remove wheel from build (#86040)

* Raise min setuptools for license specifier

Raises the minimum setuptools version used for our build requirements to
support the new license identifiers. This removes a deprecation warning
emitted by setuptools and will avoid breaking the build when the old
format is eventually removed.

* Fix typos referencing PEP 639 in text

The respective metadata docs are
* https://packaging.python.org/en/latest/specifications/pyproject-toml/#license
* https://packaging.python.org/en/latest/specifications/core-metadata/#license-expression
