Add Nyankole and Luganda languages for Tembele, an Oscar submission

Tembele (2022), Uganda's submission for the 2023 International Feature Oscar, is in Swahili, Nyankole, and Luganda, according to the director. However, I could not add the latter two. I was especially surprised to find Luganda, the most widely spoken language in Uganda with millions of speakers, wasn't available. The name for Nyankole seems to vary a lot, with alternatives including "Nyankore", "Runyankole", "Runyankore", and "Nkore", but "Nyankole" is the one used by the Library of Congress and SIL. (These sources give "Ganda" for the other language, but "Luganda" is more common as far as I can tell.) Please make them available.
