Support for Multilingual Documentation in dartdoc

Feature Request: Multilingual Documentation Support

I would like to request a feature that enables multilingual support for documentation generated by dartdoc. Currently, dartdoc generates documentation in a single language, but many developers work on projects that require support for multiple languages.

Use Case:
For example, I have a Dart project where the primary documentation is in English, but I want to provide translations in Persian (Farsi) and other languages for a broader audience.

Suggested Implementation:

1. Adding support for localization files (such as .arb, .json, or other formats) to store translated strings.
2. Providing an option in dartdoc_options.yaml to specify available languages.
3. Generating language-specific documentation in separate folders (e.g., docs/en/, docs/fa/).
4. Including a language switcher in the generated HTML output.

This feature would greatly enhance the usability of dartdoc for international projects.
Would this be possible to implement? I appreciate any feedback on this idea!

This would be possible to implement, but would be a large effort.
