Description

Enable the block editor to request and respond to changes to the network
connection status within the host app.

To test: Smoke test the editor, verify it does not crash.

Regression Notes

1. Potential unintended areas of impact
   The bridge changes could cause the editor to fail to load.
2. What I did to test those areas of impact (or what existing automated tests I relied on)
   Smoke tested the editor.
3. What automated tests I added (or what prevented me from doing so)
   None. There is no existing test files for the bridge module. Historically,
   we focus tests on the JavaScript counterparts in Gutenberg.

PR submission checklist:

• I have completed the Regression Notes.
• I have considered adding unit tests for my changes.
• I have considered adding accessibility improvements for my changes.
• I have considered if this change warrants user-facing release notes and have added them to RELEASE-NOTES.txt if necessary.

UI Changes testing checklist:

• Portrait and landscape orientations.
• Light and dark modes.
• Fonts: Larger, smaller and bold text.
• High contrast.
• VoiceOver.
• Languages with large words or with letters/accents not frequently used in English.
• Right-to-left languages. (Even if translation isn’t complete, formatting should still respect the right-to-left layout)
• iPhone and iPad.
• Multi-tasking: Split view and Slide over. (iPad)

LGTM. I was able to test successfully via WordPress/gutenberg#56609 (review). 🚀

This will be incorporated in #22112 as it includes required bridge methods whose absence will cause CI failures.
