Improves debugging for events config + fixes inconsistencies in events.json (#93595)

## About The Pull Request

If an event is not found in the list, it will be null, so the stack
trace when there is an invalid one in there will always return "Invalid
event attempting to be configured." AKA nothing useful to indicate which
event in the config is actually causing the failure.

Also stops stack trace from declaring 'invalid' config when they are
simply not loaded due to the current map.

It should be printing out [variable] instead.

Also removes a bunch of non existent events from the events.json and
fixes a few inconsistencies with the default weights.

## Why It's Good For The Game

Stack traces with useful information are good.

## Changelog

Nothing player-facing
