bump activerecord to fix cve-2025-55193

Dependabot flagged `activerecord` in
`driver/riverqueue-activerecord/Gemfile.lock` as vulnerable for versions
`>= 8.0, < 8.0.2.1` (CVE-2025-55193). In this repo, the ActiveRecord
driver lockfile previously resolved to `activerecord 8.0.1`, which falls
inside that vulnerable range.
