Reduce intl constraint to match flutter_localizations 3.16.0

[kuhnroyal]

Connection with issue(s)

See https://github.com/joanpablo/reactive_forms/commit/839968f596058c5466b61fd37a2dde56f03b4e29#r141272235

The flutter_localizations package from Flutter SDK 3.16.0 forces intl: 0.18.1 - see https://github.com/flutter/flutter/blob/3.16.0/packages/flutter_localizations/pubspec.yaml#L11

Solution description

I reduced the constraint and added the flutter_localizations package as additional dependency to ensure this does not happen again. This should have no impact on consumers of the package as the Flutter SDK is already required.

Hey @kuhnroyal Thanks for the PR, but would you mind to remove the dependency to flutter_localizations and just lower the intl version? Thanks in advance

I added that explicitly to prevent the same problem in the future. This has zero impact on users of the reactive_forms as it is an SDK dependency which does not have to be downloaded and will get tree-shaken if not used.

If you still want me to remove it, let me know.
