Removes these two discontinued plugins from `dev/integration_tests/flutter_gallery`
[`device_info`](https://pub.dev/packages/device_info):
Apparently the video playback doesn't work on iOS simulators (I wasn't able to verify this, as I don't have an iOS simulator installed). I removed the guard against running on those simulators, and replaced with a note in the README.
[`connectivity`](https://pub.dev/packages/connectivity):
This plugin was used to play the bee video from the network. I changed the demo so that the bee video is instead also played from an asset (like its friend the butterfly), and then removed the use of the plugin.
Unblocks the re-land of https://github.com/flutter/engine/pull/53462 (itself a reland ð), because of https://github.com/flutter/flutter/pull/150465#issuecomment-2181403712.
Manual recreation of https://github.com/flutter/flutter/pull/148911
Entire PR is just the output of
```
flutter update-packages --force-upgrade
```
followed by (run from the root of the flutter repo)
```
find . -type d -name 'android' | dart dev/tools/bin/generate_gradle_lockfiles.dart --no-gradle-generation --no-exclusion
```
Unpins flutter_plugin_android_lifecycle where it is pinned. I then
1. ran `flutter update-packages --force-upgrade` (but only committed the changes within `dev/integration_tests/gradle_deprecated_settings/`, which is where it had been pinned)
2. followed by `./gradlew :generateLockfiles` from `dev/integration_tests/gradle_deprecated_settings/android/` (the lockfile was what was causing the CI dependency resolution failure, so this second step is the fix for that).
See the reason it was pinned: https://github.com/flutter/flutter/pull/121847#discussion_r1124797112 followed by the PR that pinned it: https://github.com/flutter/flutter/pull/122043
