Support deep linking to documentation from tools + RP

[rynowak]

It would be really helpful for us to have the capability to "deep link" from tools and error strings into the docs. Usually this is done with some kind of link shortener. We can't key this purely on our error codes because we're encouraged to reuse some "common" ones from ARM. eg: we can't guarantee that every error code maps to a single help topic.

As soon as we have this capability we can start using it, which will cause us to think very holistically about how we're explaining problems to users.

We could use aliases to add easy to read words to specific pages. For example, we could add "environments" as an alias of https://edge.radapp.dev/operations/managing-envs/, and then https://radapp.dev/environments would link to that page
