Add Haml pre processor

[RobinMalfait]

This PR ensures we extract candidates from Haml files.

Fixes: #17050

I just tried this on the insiders track and it is mostly working!

Unfortunately, I'm still having some odd troubles.

For example %h3.mt-24.text-center.text-4xl.font-bold.italic does everything but the .mt-24. I tried removing the %h3 so that it was just a div, but no luck.

I'm going to clone the repo and see if I can add some tests to do some more debugging and see if I can come up with additional tests that would be helpful.

Thanks for your work on this! 🙌

@topherfangio with just the input you shared it seems to work for me. Can you check 2 things for me:

1. Is this happening in a .haml file or another file?
2. The context around this is important, so can you share the full file this is happening in?

If you can come up with a fix that would be nice, if not, a new GitHub issue with a minimal reproduction repo attached would be appreciated. That way we can link to the issue in the new PR and keep it easier to track issues 👍

I cloned the project and am tying to get started with it but running into some issues.

I'll try to put together a repo that reproduces it, but in the meantime, you can see the failing HAML file here: https://github.com/profoundry-us/loco_motion/blob/main/docs/demo/app/views/application/home.html.haml

Thanks for looking into this!

@RobinMalfait Here is the reproduction URL.

I tested a handful of other classes, and the only one I noticed missing was the mt-24. Seems like it got everything else (so far).
