Skip baseline checks for some complex_graph patterns

This temporarily suppresses baseline comparisons for two patterns
where the baseline checks fail if the `complex_graph` fixture
script was run in Git 2.47.0.

For now, they are unconditionally suppressed, regardless of the Git
version or whether generated archives are used. This change is
specific to the `find_youngest_matching_commit::regex_matches`
test.

This works around, but does not fix, issue #1622. The affected test
is still run, but the two directly affected baseline checks are
skipped.
