Solving ModResolutionException regarding Night Config

Older versions of FCAP sometimes ran into issues regarding the way the utilized Night Config library was shipped with the final mod. In a development environment upon running the game this could lead to you being greeted with the following error message:

net.fabricmc.loader.impl.FormattedException: net.fabricmc.loader.impl.discovery.ModResolutionException: Mod resolution encountered an incompatible mod set!
A potential solution has been determined:
	 - Install com_electronwill_night-config_core, any version.
	 - Install com_electronwill_night-config_toml, any version.

To resolve this issue, manually add Dependency Overrides to your run configuration. Do that by creating a new file at run/config/fabric_loader_dependencies.json, in which you put the following contents:

{
  "version": 1,
  "overrides": {
    "forgeconfigapiport": {
      "-depends": {
        "com_electronwill_night-config_core": "",
        "com_electronwill_night-config_toml": ""
      }
    }
  }
}

Also don't forget to manually add this file to your VCS, since the whole run directory is usually ignored by default. A dedicated common publication does not exist for these versions.
