Links: Multilanguage slugs

[tomasciccola]

This document describes how slugs for different languages should be handled:

From notion, when a person that creates a link in a certain language, does it relative /docs/ ommiting the language code. For example:
linking from notion to /docs/desinstala-comapeo should link to docs.comapeo.app/es/docs/desinstala-comapeo.
I'm guessing we already have a way of knowing the language of a particlar page, since from the link in notion it doesn't reveal it.

Additionally every accent and additional symbol present in latin languages (á,é,ñ and f.e. portuguese accents) should be removed from the link. Regarding this, the person that creates the link from notion, may remove this characters, but we should also handle the removal ourselves, just in case

This behavour should also apply to internal page links (hashtag links)

This issue has been resolved in #170. Here is a brief summary of how it was solved:

• Robust Unicode Slugification: Implemented Unicode property escapes (\p{M}, \p{L}) and .normalize("NFD") to strip diacritics while preserving international characters safely.
• Explicit Heading IDs: Injected explicit Docusaurus heading IDs ({#id}) to forcefully bind the generated anchor to the sanitized slug logic, ensuring reliable linking.
• Smart Link Interception: Normalized absolute internal documentation links (e.g., /docs/.../) during the block generation pipeline to correctly inject the current locale prefix, fixing cross-language navigation.
