Submodule breaks page source links

[andrewdavidwong]

I've created links to view and edit the source of every page using the "doc" layout. These links work beautifully for pages which reside in the primary qubesos.github.io repo, but they fail for all pages which reside in submodules (e.g., qubes-doc).

Current working examples:

• https://www.qubes-os.org/
• https://www.qubes-os.org/downloads/
• https://www.qubes-os.org/en/news/

Current broken examples:

• https://www.qubes-os.org/en/doc/
• https://www.qubes-os.org/en/doc/getting-started/
• https://www.qubes-os.org/en/doc/system-requirements/

(Look in the upper right-hand corner for the "Source" and "Edit" links.)

Options:

1. Create separate layouts for the pages in qubesos.github.io and the pages in submodules, and have the submodule layout use page.relative_path instead of page.path. But we'd still need a way to grab the correct repository_url.
2. Move the pages in qubesos.github.io to qubes-doc, and continue to use one layout (the "doc" layout) for everything, then make the other changes stated in 1.
3. Stop using submodules, and instead have all pages in qubesos.github.io (least likely option).
