languages/typst: Add inline preview via typst-concealer (#588)

* add typst-concealer

* Update modules/plugins/languages/typst.nix

Co-authored-by: raf <raf@notashelf.dev>

* add keybinds, resolve review etc

* add changes back (it was easier than a rebase here)

* add the newer conceal_in_normal option

* run deno fmt

* add "typ" to typos
