py-webcolors: updated to 24.6.0

Version 24.6.0

* Supported Python versions are now 3.8, 3.9, 3.10, and 3.11.

* Running the unit tests no longer uses a third-party test runner; the
  standard-library ``unittest`` module's runner is used instead.

* Documentation of the HTML5 color algorithms has been updated to emphasize
  which HTML5 spec is used (the WHATWG spec, which is now the only canonical
  and maintained HTML5 spec) and comments in the implementations have been
  updated to include the latest prose description of the HTML5 algorithms from
  the spec. These updates do not change the behavior of the HTML5 algorithms,
  and are only for clarity of documentation and explanation.

* Adopted `CalVer versioning <https://calver.org>`_.

* The raw mappings of color names/values are no longer publicly exposed; use
  the appropriate normalizing conversion functions instead of accessing the
  mappings directly.
