This slipped through the 1.21.11-1 -> 7.0.0 bump in
6c359d6488.
Upstream made this a noop with a deprecation warning instead of a
hard fail in https://codeberg.org/forgejo/forgejo/pulls/2864.
Note: In that PR (it's commit) they link to nixpkgs as downstream
consumer of it (`build/merge-forgejo-locales.go`).
