Revert "mimir: 2.4.0 -> 2.5.0"•••This reverts commit 4e371517033d31305a50509004bd3a7003a26afe.
This broke the build as the source now returns 404.
The script seems also more bloat over just using `nix-update --commit --build mimir`
electron: add missing wayland runtimeDependency (#206978)•••when using --ozone-platform-hint=wayland it will dlopen this library.
Adding wayland to rpath does not increase the closure size since gtk3
already should have wayland in its closure.
This fixes element-desktop for example.
