Fix transliteration for metadata + transliterate select options (#5430)

## Context 
Fixes #5403

Transliteration is now integrated to form validation through the schema.
While it does not impede inputting an invalid value, it impedes
submitting a form that will fail as the transliteration is not possible.
Until then we were only performing the transliteration at save time in
the front-end, but it's best to provide the information as soon as
possible. Later we will add helpers to guide the user (eg "This name is
not valid": https://github.com/twentyhq/twenty/issues/5428).
