The launcher is not available in catalan(Catalunya)

The latest versions of the launcher are not available in Catalan (Catalunya), but is available in catalan (València), wich are two different dialects of catalan I hope you to add Catalan (Catalunya) in the launcher, and also, Catalan (Catalunya) is available in Mincecraft java but Catalan (València) is not.
