Enable Edit button only on pages whose source of truth is the documentation site

[vadasambar]

Problem statement

We are supporting Editing all the pages on our documentation website (PR) but this might create a problem where a user wants to edit the auto-generated CLI docs (for example) or docs pulled from another repository (i.e., actual source sits somewhere else) but the edits would be over-written in the next auto-generation (or pull from the source).

Describe the solution you'd like

The Edit button should be shown only on the pages which sit in our documentation site repo and are written by hand.

Describe alternatives you've considered

We could put a big warning against docs where the source of truth is not the documentation site repo.

Hey @vadasambar can I work on this issue?

[vadasambar]

Sure. cc: @iamrajiv because he wrote most of the code in this repo.

@iamrajiv , I am not sure if we support auto-generation of docs using CLI in this repo yet and if the answer is no, this issue might be irrelevant (we might have created this issue with future scope in mind)
