Fix small errors in input file docs

[tsmbland]

Description

Fixes some small errors/omissions in the docs (some flagged in #820) that didn't warrant their own individual issues

Any ideas how we can automatically flag errors like this/keep this in sync with the code?

LGTM!

I was thinking we could automatically validate the schemas with a script (#623). I have made a start, but other things got in the way. I suppose we're not doing lots atm, so maybe I could have another look at it...

I think the schemas should be validated at some point to ensure they align with the input data. As of now, the schemas and the code are rather disconnected.
