Support for (Forge) configuration files/menu

[KlemenDEV]

Migrated from https://mcreator.net/tracker/issue/53297

In the Mod Options, when we click on Esc, there is all mods installed, and when we click on them, there is a Configuration button. So, I would like to have an option into MCreator to add some a mod element or something else to add configuration options. I find some links to help you to implement this feature. I know that the first link can be a little bit outdated, but it can help you with the base.

This should likely be a new tab similar to the global variables tab in the workspace view.
