Add Albanian (sq) language support to navigation.languages

[jorgejunior-mk]

We'd like to add Albanian documentation to our Mintlify site using the sq language code, but the navigation.languages[].language field currently validates against a fixed enum that doesn't include it.

Would it be possible to add sq (and potentially sq-AL) to the supported language list? All other aspects of our setup are in place — translated content and navigation config are ready to go.
