fix(context-actions): fix off by one context actions

[sudo-tee]

There was 2 off by one errors when adding contextual actions

When adding them in snapshots

When refreshing them after a part update

A couple of test needed to be regenerated for it to work

I added the possibility to regenerate a test snapshot by it's name or file-name

@cameronr When you have a chance, can you do a quick check/review on this.

I was not seeing the context action on restore points anymore and I investigated.

This is my attempt at fixing it.

Ah, I see the issue. When I added the extra newline at the end, I didn't account for that for actions. I didn't catch it with the replay tests because they needed to be regenerated for the newline so I missed that the actions were off after that change.

I think there's also some inconsistency on whether actions should be 0 indexed or 1 indexed. according to :h api-indexing most nvim functions are line 0 indexed with some notable exceptions, including nvim_win_get_cursor. I think we should standardize on api-indexing.

If that all sounds good, I'll fix the root issue and clean up the indexing to be consistent.

Also, the replay tool has a :ReplaySave command which is what I've used to update a single output. The idea is that you can save the output once you reviewed it to be correct.

Sure If you want to fix the root cause I'm all for it.

It was confusing indeed, and the -1 indexing is also confusing

thanks for your help

Was finally able to push my changes after GH resolved it's issue.

The main changes are here, with the underlying fix being in renderer.lua:

4099a8f (#124)

[cameronr]

I guess I spoke too soon, the tests failed because GH is still having issues. I'll rerun the tests

Thanks for the fixes :)
