feat(manager): add Try Update button for nightly packs (#7610)

## Summary
- Add "Try Update" button in InfoPanel for installed nightly packs
- Allows users to pull latest changes from repository for nightly
versions
- Nightly updates cannot be auto-detected (git hashes vs semver), so
users trigger manually

## Test plan
- [x] Install a nightly version of any pack
- [x] Select the pack in Manager
- [x] Verify "Try Update" button appears in InfoPanel
- [x] Click "Try Update" and verify update request is sent
