fix: use releases API in check_lance_release.py (#3427)

Previously `check_lance_release.py` used `git/refs/tags` with
`--paginate --jq`, which drops the last page in some `gh` versions. The
7.x Lance tags all landed on the final (partial) page, causing the
script to report `v6.0.1` as the latest and never triggering an update.

Switch to the releases API with `per_page=20`, which returns the 20 most
recent releases sorted newest-first — one API call, no pagination
needed.
