Add support for Flutter 3.3.10 with internationalization

[AlwinFassbender]

I'm using the flutter beta channel version 3.10.0-1.1.pre.

This leads to following issue with flutter pub get:

[your_app] flutter pub get
Resolving dependencies...
Because your_app depends on flutter_localizations from sdk which depends on intl 0.18.0, intl 0.18.0 is required.
So, because your_app depends on intl ^0.17.0, version solving failed.
exit code 1

Using intl ^0.18.0 leads to this:

[your_app] flutter pub get
Resolving dependencies...
Because no versions of firebase_auth match >4.4.1 <5.0.0 and firebase_auth 4.4.1 depends on firebase_auth_web ^5.3.1, firebase_auth ^4.4.1 requires firebase_auth_web ^5.3.1.
Because firebase_auth_web 5.3.1 depends on intl ^0.17.0 and no versions of firebase_auth_web match >5.3.1 <6.0.0, firebase_auth_web ^5.3.1 requires intl ^0.17.0.
Thus, firebase_auth ^4.4.1 requires intl ^0.17.0.
So, because your_app depends on both firebase_auth ^4.4.1 and intl ^0.18.0, version solving failed.
exit code 1

It works with overridden dependencies for now, but it would be neat to get a version update for firebase_auth as soon as possible. Is there already a plan on when this is going to happen?
