{ibus,fcitx5}-rime: Refactor RIME data support

nixos/doc/manual/release-notes/rl-2305.section.md

@@ -128,6 +128,8 @@ In addition to numerous new and upgraded packages, this release has the followin
 
 - The [services.unifi-video.openFirewall](#opt-services.unifi-video.openFirewall) module option default value has been changed from `true` to `false`. You will need to explicitly set this option to `true`, or configure your firewall.
 
+- The option `i18n.inputMethod.fcitx5.enableRimeData` has been removed. Default RIME data is now included in `fcitx5-rime` by default, and can be customized using `fcitx5-rime.override { rimeDataPkgs = [ pkgs.rime-data, package2, ... ]; }`
+
 - Kime has been updated from 2.5.6 to 3.0.2 and the `i18n.inputMethod.kime.config` option has been removed. Users should use `daemonModules`, `iconColor`, and `extraConfig` options under `i18n.inputMethod.kime` instead.
 
 - `tut` has been updated from 1.0.34 to 2.0.0, and now uses the TOML format for the configuration file instead of INI. Additional information can be found [here](https://github.com/RasmusLindroth/tut/releases/tag/2.0.0).
