Check docs are updated in prs

Fixes #66

This adds a check that docs are generated when commands are added and changed!

Thank you for working on this Charlie.

At the moment these docs are jsctl's only documentation, so I think ./docs should have docs for the latest released version of jsctl, not the latest main. This check would force us to do the latter. I think it would be better if instead we had automation to PR docs updates against this repo as part of release process #66 (comment)

Ahh, that's what was meant in #66. I wasn't sure but thought that this made sense anyway.

I personally still think this is the right thing to do for now. It seems odd to me for the docs in the repo to not match the state of the code at that same version. I think that's a desirable property.

The reality is that a user landing on the repo looking for docs is that they could be using any version, rather than the latest release.

I agree that it'd be nice to make it possible to browse different versions of the docs site. However, for now, I still feel this is a step in the right direction.

match the state of the code at that same version

I've come to see your point yeah. We can always link the docs at a specific tag for a specific release.

Thanks for working on this!
