Make codesnippets in the docs typechecked

[rpanic]

The rust node's documentation extracts code snippets in the docs from the actual codebase (or some derivative of it - not sure). This means that they are always typechecked and preferably part of some test that is also run during CI.

See https://o1-labs.github.io/mina-rust/docs/developers/referencing-code-in-documentation and https://o1-labs.github.io/mina-rust/docs/developers/ocaml-reference-tracking
And https://github.com/o1-labs/mina-rust/blob/develop/.github/workflows/docs.yaml#L54-L77
And https://github.com/o1-labs/mina-rust/blob/develop/.github/workflows/check-ocaml-refs.yaml

For us, a good end goal would be if during a protokit release, a workflow for the website is triggered, that compiles and runs the code snippets based on the new release, and then rebuilds and deploys itself. This means that we will receive errors as soon as the docs contain outdates code snippets
