Update bridge dependencies to final deprecated versions

- share2nightscout-bridge: 0.2.9 → 0.2.10 (Node 22 support)
- minimed-connect-to-nightscout: 1.5.5 → 1.5.6 (Node 22 support)

Both packages now allow Node 18/20/22+ in their engines field.
This is a prerequisite for the Node 22 upgrade (PR #8357).
