feat(i18n): add Hungarian translation for Authenticator component

[szilvia-csernus]

Description of changes

Added complete Hungarian (hu) language support for the Authenticator component. This includes translations for all authentication flows, form fields, buttons, error messages, and validation text.

Changes include:

• New Hungarian translation dictionary (packages/ui/src/i18n/dictionaries/authenticator/hu.ts)
• Integration of Hungarian translations into the main translation system
• Updated documentation to list Hungarian as a supported language
• Changeset for minor version bump of @aws-amplify/ui package

Hungarian-speaking users can now use the Authenticator component in their native language by calling I18n.setLanguage('hu').

Issue #, if available

N/A - This is a new feature contribution adding language support.

Manual Testing:
