test: ignore latest_version_hint.json in manifest dir assertions

Browse Source 
Lance v7.0.0-rc.1 writes _versions/latest_version_hint.json on
non-lexically-ordered stores (e.g. the local filesystem) to speed up
latest-version lookup. The V2-manifest-path tests iterate the whole
_versions directory and asserted every entry matches the manifest
filename pattern; filter to *.manifest files so the hint file is ignored.
