Reference Sourcegraph learn in-product

Created by: malomarrec

Idea

Sourcegraph learn has lots of resources for new users to learn about the search syntax. Use learn pages for specifc use cases. Could we make use of that in-product, in the context of a specific use case? We can detect search query patterns that need a specific help page. For example, we could point to specific Sourcegraph learn pages in error messages.
