Subject: [PATCH] tests/sphinx-markdown-changelog: work around shallow clones
 in CI

GitHub CI uses shallow clones where no Git tags available, which
breaks tests/checks/sphinx-markdown-changelog.fish.

Somehow tests/checks/sphinx-markdown-changelog.fish doesn't seem to
have run CI before the next commit (or perhaps the python3 change
from commit "tests/sphinx-markdown-changelog: workaround for mawk",
2025-10-26?).

Anway, to prevent failure, disable that part of this test in CI
for now; the point of the test is mostly to check the RST->Markdown
conversion and syntax.
