Fix version in circuitpython-stubs

[jepler]

the configuration that tried to use setuptools_scm was broken. Instead, provides circuitpython-stubs' setup.py with the version determined by setuptools_scm running in the git source directory.

This gets rid of the following message seen during the doc build in github actions:

WARNING setuptools_scm.pyproject_reading toml section missing 'pyproject.toml does not contain a tool.setuptools_scm section'
Traceback (most recent call last):
  File "/tmp/build-env-dsk5kdxt/lib/python3.12/site-packages/setuptools_scm/_integration/pyproject_reading.py", line 36, in read_pyproject
    section = defn.get("tool", {})[tool_name]
              ~~~~~~~~~~~~~~~~~~~~^^^^^^^^^^^
KeyError: 'setuptools_scm'

Compared to the version originally in #9947 this adds fetching tags during the doc build.

Remember to also check if this worked on RTD!

Thank you for figuring out that mysterious error!
