Fix/docs

[alessandrojcm]

Got docs to compile again. Although they work, they (obviously) still need updating. Also, two things:

• Changes to the code highlighting made some parts of the docs look odd, the line break between text and the code block doesn't look good IMO. For this I think we should use InlineCodeHighlight
• There is a weird pre-rendering error with SourceCodeSnippet, the Select for the theme shade uses the default shade from the useMantineTheme hook which is for some reason not present a build time. I have added a ?? operator and hardcoded the shade so it works; not ideal but it works.

A member of the Team first needs to authorize it.
