[FABRIC] Adding the Playit Companion mod WITHOUT fabric api returns error.

You should probably make sure that the fabric loader indicates that fabric API is required (in the error popup that fabric does, it doesn't indicate that fabric api is required specifically


also you may want to flesh out the modrinth page description slightly, as its not clear (besides the tags) that people do not require server software and that they can use playit within a singleplayer world
