Update 'Edit this page' link to point to correct project repo

Add support for a custom page param that can be used to point the
links in the sidebar to the correct project repos.

'Edit this page' will open the editor pointing to the correct file
in the project repo, instead of trying to find it in the website repo.

'Create an issue' will open the new issue UI in the target project repo.
