Description of changes

This one is for you @nderjung

If we want this to work properly we need to add some custom dictionaries to make sure that words like unikraft and kraftkit, etc. are caught

We can add single exceptions, but I think it warrants a dictionary. Examples: https://github.com/check-spelling/check-spelling/wiki/Feature:-Area-dictionaries

We should not merge until then

Thanks 😇 But is this not already enabled via golangci-lint ?

I think that is for variables only? Comments are for sure ommited.

Anyways, this is just an idea right now, they don't really say how this should be structured so I just tried some things

Converting to draft cause it doesn't really work, also is not that urgent
