Drop test_default_base_url_matches_spec_servers as tautological

The committed openapi.json's servers[0] path is whatever URL the
spec was fetched from. CONTRIBUTING.md hardcodes that fetch URL,
and test_spec_path_matches_default_base_url already pins
DEFAULT_BASE_URL.path into CONTRIBUTING.md and spec-drift.yml.
Under the documented regeneration workflow the spec path equals
DEFAULT_BASE_URL.path by construction; the only failure modes
left are manual fetches from a wrong version or version bumps
without regenerating, both of which code review catches.
