Migrate to android v2 embedding

[nohli]

There is a warning regarding the v2 migration during every flutter build, even just on pub get.

The other plugins were really quick with updates - this is (for me) the last plugin that hasn't been updated yet.
A new version on pub.dev would be great! :)

This PR fixes it.

@sanekyy @kakudenbuzo could you also test it on a real Android device before it gets merged/published?

Just to be clear, this is the exact warning message shown

The plugin `flutter_vibrate` uses a deprecated version of the Android embedding.
To avoid unexpected runtime failures, or future build failures, try to see if this plugin supports the Android V2 embedding. Otherwise, consider removing it since a future release of Flutter will remove these deprecated APIs.
If you are plugin author, take a look at the docs for migrating the plugin to the V2 embedding: https://flutter.dev/go/android-plugin-migration.

This branch has no conflicts. Please merge soon 😄
