fix: Remove throwing an exception if appId/bundleId is not provided

[AhmedLSayed9]

Description

If a platform's appId/bundleId is not provided, an exception will be thrown inside a CI environment.

There was a partial fix for the mandatory flag by https://github.com/invertase/flutterfire_cli/pull/179 but it's not completely fixed as an exception will still be thrown:

This should fix https://github.com/invertase/flutterfire_cli/issues/233
