Had to use "Create Version Control Metadata" to activate plugin

Godot v4.0.4.stable.official [fc0b241c9], plugin v3.0.0.

Yesterday I created a new project in an attempt to reproduce a crash that I had previously experienced with the plugin. (I was unable to reproduce the crash.)

I followed the instructions in the [Wiki](https://github.com/godotengine/godot-git-plugin/wiki/Git-plugin-v3).

The plugin was not "activated" until I did this: Project >> Version Control >> Create Version Control Metadata.

If that's the normal procedure, it should be clarified in the instructions, since it's not obvious. "Metadata" sounds like something that's optional.

v.2.1.0 of the plugin has Project >> Version Control >> Set Up Version Control, and the popup dialog has the Initialize button, which is clearer.

Maybe rename "Create Version Control Metadata" to "Initialize", and disable or remove it after it's been done? Or rename "Initialize" to "Re-initialize" after the initialization has been done, if that's a needed feature.
