sphinx-lint now ignores default roles in docs' make check

[ezio-melotti]

We have a GitHub workflow for documentation that runs make check:

cpython/.github/workflows/doc.yml

Lines 43 to 44 in 7d7a378

	- name: 'Check documentation'
	run: make -C Doc/ PYTHON=../python SPHINXOPTS="-q -W --keep-going -j4" check

make check runs

cpython/Doc/Makefile

Lines 215 to 217 in 7d7a378

	check:
	$(SPHINXLINT) -i tools -i $(VENVDIR) -i README.rst
	$(SPHINXLINT) ../Misc/NEWS.d/next/

By default sphinx-lint only reports errors with a severity >=1:
https://github.com/sphinx-contrib/sphinx-lint/blob/b25d09c5a0cf15030c575d18078d815724a1e3e0/sphinxlint.py#L453-L459

The severity of the "default role" check (i.e. making sure that no single `...` are used), was recently changed to severity=0 in sphinx-contrib/sphinx-lint@999b43d.

This means that the use of the default role is no longer caught as an error by make check.

See also #86404.

Did you land all the backports; can we close this?

[ezio-melotti]

Yes, I ported it to 3.11 in #92821 and previous versions were not affected since they used Tools/rstlint.py.
