[google_sign_in_web] Updates package:web dependency to 0.5.0. (#6167)

This PR updates `google_sign_in_web` to use package `web: ^0.5.0`.

## Testing

Manually verified using the `example/lib/button_tester.dart` app.

This should be text exempt? This is a refactor with no semantic change (also, I wouldn't know how to test we're using `package:web` the expected way!) I removed a couple of `//ignore` at least!

## Issues

* Fast follow of: #5791
