Feat #879: Note Embedding Syntax

[badsketch]

Addresses #879

• deprecates foam.preview.noteEmbedInContainer
• adds syntax discussed. I added comments in the code, but basically the regex plugin for markdown-it only supports one group, which is currently just the wikilink. Therefore I need to capture the entire wikilink item (all of content-card![[note-a]]), and then have another regex that does the parsing and grouping to extract the modifier and the wikilink. This leads to a bit of messy regexes, but I added tests to try to confirm their validity.
• is not order agnostic, so full-card![[note]] would match both modifiers, whereas card-full![[note]] wouldn't recognize the card portion and just parse the full part. 🫤 I could make it recognize both, but it would require expanding the existing regex, which could get ugly. Then again, the existing behavior might confuse users.

Let me know if this is what you had in mind!

Testing

Given we have content-inline as the user setting

Case 1: no type modifiers should just default to the user setting

Case 2: adding a type modifier content should not have an effect since it's already the default

Case 3: adding one modifier card should override inline resulting in card-inline style

Case 4: adding two modifiers full-card should override both default style and scope resulting in full-card style

This looks good to me! Only thing I would ask is to add documentation for the feature in the docs folder

Updated docs, so lemme know your thoughts on wording, formatting, etc.!
