docsy: Updating Docsy moves navbar to the left (wrong) side

Hi there, I just updated Graphviz to the latest Docsy with git submodule update --remote, now the table of contents is on the wrong side of the screen:

I suspect this is related to #554 merged 2 days ago, because that commit changed the navbar HTML layout from a <div> tag to an <aside> tag: https://github.com/google/docsy/pull/554/files#diff-4a7bcb5855bcc928f61527aba2cb16f957266b13ab51553e46016c82ac8c4dd2R16. But I haven’t looked into it further than that yet.
