feat: BAML gem supports ruby 3.4 (#1804)

`baml` gem now supports ruby 3.4

1. Update runtime_test.rb to find integ-tests relative to file instead
of hardcoded path.
2. Update github workflow to include ruby 3.4. Currently suffers from
the same pinning issue, will follow up with another PR to have it be
unpinned to 3.4. But at least this unblocks ruby 3.4.
3. bump Gemfile.lock to latest baml gem
