"Edit on GitHub" button should link to the specific markdown file for that page

[htroisi]

Current behavior

The docs.px.dev site contains an "Edit on GitHub" button in the bottom-right hand side of the footer. Clicking this button will take you to the top-level folder in this repo, no matter what page you are on in the docs site.

Desired solution

Ideally, the "Edit on GitHub" button would link to the markdown file for the specific content page that is open.
