refactor: embed localized language names in 'info.php'

Add a 'localized_names' array to 'src/info.php' mapping language identifiers to human-readable names and remove the now-redundant 'src/lang_lang.php'. This centralizes language name definitions in the module info file to reduce duplication and simplify lookups.
