feat(#2350) Allow relative paths in markdown in docs.

[shawnsarwar]

Description

The patch addresses #2350 : and allows the use of relative paths for links and images in the docs section of collections and requests.

Given this doc string:

The current version cannot display the relative path, but can display the image with a full path.
The rendered html is:

With this patch, the rendered HTML is now correct and the client displays the image:

note! this is hard to replicate on the dev environment because (at least on my machine) neither relative or full path images can be displayed. I suspect this is an issue with permission and electron. Building for your environment through the correct npm action should allow you to validate the behavior.
