Do a full review of docs to uniformly apply previous partial fix of param docs

Additional note: I just realized that in the chapter documenting how to enable GCSE search engine, the line gcs_engine_id = "xxxx" should be within params as well. We should address this in a separate ticket/PR IMHO.

Maybe there should be a full review, because there are more references without the params indications :

• https://www.docsy.dev/docs/adding-content/lookandfeel/#code-highlighting-with-prism
• https://www.docsy.dev/docs/adding-content/repository-links/

Thanks for the suggestion. /cc @svrnm
