Problem

This issue is described here https://stackoverflow.com/questions/78754682/docsy-edit-link-are-generate-with-local-absolute-path. Basically, the "View page source", "Edit this page", and "Create child page" hyperlinks are broken when doing hugo build on Windows. I think this may have broke with this commit https://github.com/google/docsy/commit/435b2e0678694f3812a285a67dfac43f1c8ddd25 released in Docsy 0.9.0 because it adds a forwardslash to hugo.WorkingDir when creating the trimmed path for the file in the page-meta-links.html template. This was working fine on Hugo v0.115.3 and Docsy v0.7.1 but I noticed it broke when I tried to update to current latest (Hugo v0.138.0 and Docsy v0.11.0)

Easily reproducible by cloning https://github.com/google/docsy-example on Windows and running hugo or hugo serve. You'll notice the hyperlinks for "View page source", "Edit this page", and "Create child page" are paths like

Rather than the expected
