Localization broken

[zanhk]

Something in the last updates seem to have broke localization.

Change localization system, probably to https://github.com/jlarmstrongiv/astro-i18n-aut until astro implement a standard way to localize (ref. withastro/roadmap#734 (comment))

Still waiting for withastro/roadmap#787, right now there no really a point to switch as it would need more refactor code and would require more effort to mantain.

Waiting for a standard solution.
