Migrate to firebase v9 modular sdk

thatfiredev commented 2 years ago

Description

This PR should update geofire to use the new modular firebase sdk (v9). I simply copied the changes from #217 and made small improvements with as little code changes as possible to fix the build. These include:

replace the uglify plugin with terser
use the stable version of firebase v9 instead of the beta
bump the node version on GitHub actions to 10.x (minimum required by v9)

TODO:

[x] Docs
[x] Migration guide
[x] Examples
[x] Remove exp version
[ ] Major version bump
