Describe the bug
pvlib.atmosphere.first_solar_spectral_correction was deprecated in v0.10.0 but it doesn't have an scheduled removal version. No issues or PRs open for it.

To Reproduce
See https://pvlib-python.readthedocs.io/en/stable/reference/generated/pvlib.atmosphere.first_solar_spectral_correction.html
And tests for https://github.com/pvlib/pvlib-python/blob/048b70ffa8a90c788491576e5057bcfc0667d8ea/pvlib/tests/test_atmosphere.py#L91C1-L94C65 do not show when it should fail.

Expected behavior
pvlib.atmosphere.first_solar_spectral_correction to have disappeared in v0.11, or the repo to have the corresponding test failures set to some version.

Versions:

• pvlib.__version__: 0.11.0
