feat: add batch query cassette for commit 17b30e96 (#4772)

This PR adds a new batch query cassette to the `apitester` tool to test
the commit `17b30e96476be70b8773b2b807bab857fd3ceb39` and captures the
current API behavior in a snapshot.

This allows us make commit queries be cassetted in osv-scanner.
