astro/py-ephem: Update to 4.2.1

- First release that offers wheels for Python 3.14
- Star database now makes the star Albereo available under its more
  official spelling Albireo
- Classes like Sun and Mercury are now defined using plain literal
  class statements, instead of being built dynamically in a for loop.
  This should make the classes visible to tools like editors,
  debuggers, and type checkers.

Strip had to be changed from PYTHON_TAG to PYTHON_SUFFIX in order to
also support threaded Python versions (3.13t).
