[BUG] GLOBAL_SCRIPTS container no longer contains all global scripts

[InspectorCaracal]

Describe the bug

The current implementation of GLOBAL_SCRIPTS, i.e. GlobalScriptContainer, does not actually contain all global scripts. It will only access global scripts that were defined in settings, rather than the previous and documented behavior of any global script.

The container class is here: https://github.com/evennia/evennia/blob/main/evennia/utils/containers.py#L94

On reviewing the code, it's evident that the entire class is designed to only load those classes that were defined in the GLOBAL_SCRIPTS variable in the game's settings, and to only load them once on first access of the data.

Expected behavior

Previous versions of GLOBAL_SCRIPTS would include all global scripts, regardless of creation method - according to the changelog, this was the case as of Evennia v0.9.5 - and the documentation here https://www.evennia.com/docs/latest/Components/Scripts.html#code-examples is written with the presumption of that behavior.

The current state, therefore, is a dramatic and undocumented regression to pre-beta functionality which somehow was not caught.

Environment, Evennia version, OS etc

Evennia v4.1.1

Curious, the container was updated to be more intuitive after the original implementation, so it should hold all global scripts.
