[PRQ#64365] Deletion Request for lua-sitegen-git

MarsSeed [1] filed a deletion request for lua-sitegen-git [2]: Dead because its legacy binary bindings dependency, lua-discount is deprecated and archived since 2023 [a] (last released in 2018 [b]), and is incompatible with the current v3.x version of the extra/discount package.
