doc: drop the special sha for the hugo theme, update hugo instead

The special sha is no longer needed, let's bump to a recent version of
hugo instead and that should make it all work nicely (for a while).

Updating hugo requires changing to hugo.toml and forcing mermaid to be
enabled, without those changes the build failed with
 `failed to extract shortcode: template for shortcode "mermaid" not found`

This reverts commit 5909717700
