Update Config page to match today's file state

[Supergecki]

Describe the bug
The config file as it is seen on the wiki Config page doesn't match the file state the config file is in today, for example the Physical friction property has been removed and replaced by distinct properties for Seekers and Goals.

To Reproduce
Just look at the files yourself and diff check them.

Expected behavior
The Config page on the wiki should explain what's going on in the config file and therefore should be up to date.

Additional context
It might be worth to look into automatic documentation here since otherwise, this issue will be repeated in the future.
