<!-- If this is a particularly complex change or feature addition, you
can request a dedicated Nx release for this pull request branch. Mention
someone from the Nx team or the `@nrwl/nx-pipelines-reviewers` and they
will confirm if the PR warrants its own release for testing purposes,
and generate it for you if appropriate. -->

## Current Behavior
<!-- This is the behavior we have today -->

When on https://nx.dev/plugin-registry the side-bar menu doesn't open on
mobile.

## Expected Behavior
<!-- This is the behavior we should expect with the changes in this PR
-->

Should obviously open. Also adjusted the top-level header menu
"Documentation" -> "Docs" (just sounds better)

## Related Issue(s)
<!-- Please link the issue being fixed so it gets closed when this is
merged. -->
