nixos.mautrix-meta: Update config to 0.4 format (#343606)

- `programs.vim.defaultEditor` now only works if `programs.vim.enable` is enabled.

- `services.mautrix-meta` was updated to [0.4](https://github.com/mautrix/meta/releases/tag/v0.4.0). This release makes significant changes to the settings format. If you have custom settings you should migrate them to the new format. Unfortunately upstream provides little guidance for how to do this, but [the auto-migration code](https://github.com/mautrix/meta/blob/f5440b05aac125b4c95b1af85635a717cbc6dd0e/cmd/mautrix-meta/legacymigrate.go#L23) may serve as a useful reference. The NixOS module should warn you if you still have any old settings configured.

- The `indi-full` package no longer contains non-free drivers.

  To get the old collection of drivers use `indi-full-nonfree` or create your own collection of drivers by overriding indi-with-drivers.

  E.g.: `pkgs.indi-with-drivers.override {extraDrivers = with pkgs.indi-3rdparty; [indi-gphoto];}`
