WIP: Add LaTex Support

[moodyjmz]

📝 Summary

• Resolves: Support Latex Math commands  #6935

This PR adds LaTeX math support to the text app.

it uses:

• Inline typing $…$
• Block typing $$…$$
• Pasting of inline
• Pasting of blocks
• Editing of both - I did consider using the same approach as inline links, the bubble, but decided to use the modal approach for both
• I added a feature into the menu to change existing content into maths - under the markup section

Code:

• I used a factory for making math nodes to avoid duplicating code
• It adds a modal, following the pattern of Image

Tests:
It adds some tests covering the features added, and issues I encountered while adding the feature

Limitations:

The existing modal doesn’t appear to be resizable - therefore here is set to largest

I wanted to see if it would push the expected files - not ready for review yet

@max-nextcloud Sorry about the confusion, hopefully this PR is better to check. It only has one commit as I took the files from the other branch.

So far we do not really have much end user documentation. I'd say we could keep it in here for now still. We probably want this to go to docs.nextcloud.com but just the math section might not be that useful.

@max-nextcloud @mejo- Something we could discuss further as you were thinking about enhancing documentation for collectives, but there may be some overlap with what we could make use of for text itself.

Very nice, I left one inline comment and there are two CI checks that need some more work to pass.

When testing the modal seems to have an issue with not taking up the full height of the textarea, but I'm unsure if that is a component issue or could be addressed here as well. Would be fine to track as a follow up for polishing:

Thanks :)

I addressed those issues.

Yes, the modal, I was unsure what caused it, but felt it was out of scope to address in this PR.
