[dshukertjr]

What kind of change does this PR introduce?

Adds a localization feature to override the OAuth provider name

SupaSocialsAuth(
  socialProviders: const [OAuthProvider.azure],
  localization: const SupaSocialsAuthLocalization(
    oAuthButtonLabels: {
      OAuthProvider.azure: 'Continue with Microsoft (Azure)'
    },
  ),
  onSuccess: (session) {
    // sHandle success
  },
),

Closes #87

Hi,
Continue with is not translated in SupaSocialsAuthLocalization, fixed that in the commit. But I don't think we need "forgot password" in supasocialsauth, removed it in the second commit. Should be simple to revert incase I overlooked something.

../lib/src/components/supa_socials_auth.dart:388:39: Error: The getter 'continueWith' isn't defined for the class 'SupaSocialsAuthLocalization'.
 - 'SupaSocialsAuthLocalization' is from 'package:supabase_auth_ui/src/localizations/supa_socials_auth_localization.dart' ('../lib/src/localizations/supa_socials_auth_localization.dart').
Try correcting the name to the name of an existing getter, or defining a getter or field named 'continueWith'.
                      '${localization.continueWith} ${socialProvider.labelText}'),

LGTM! 🚀

Great catch about not needing forgot password.

Thanks for fixing the code, and sorry that I failed to explain this, but removing the continue with was intentional.

Currently, the label on the OAuth login buttons are limited in the format of ${continueWithLocalization} ${ProviderName}, but not every language can follow the format, and I thought there should be a way to just override the entire thing.

That is why I decided to return the text including the continue with on the labelText, and now we can just override the entire button text using the new oAuthButtonLabels property.

Should be good to merge 😊
