Localization of Conan Documentation

Hello, Conan Community,

I’m glad to announce that the 🎉 **conan-docs-l10n** 🎉 project is published now:

- 🚀 **Preview:** [conan-docs-l10n](https://projects.localizethedocs.org/conan-docs-l10n)
- 🌐 **Crowdin:** [conan-docs-l10n](https://localizethedocs.crowdin.com/conan-docs-l10n)
- 🐙 **GitHub:** [conan-docs-l10n](https://github.com/localizethedocs/conan-docs-l10n)

The goal of this project is to translate the Conan Documentation into multiple languages. Translations are contributed via the Crowdin platform, automatically synchronized with the GitHub repository, and can be previewed on GitHub Pages.

I noticed that there was an issue requesting for multi-language for the Conan Documentation:

- https://github.com/conan-io/docs/issues/832

I believe this `conan-docs-l10n` project can fulfill such needs.
