Errors with WAVE-Tool

Checking the site with [WAVE-tool,](https://webaim.org/) it found 4 empty links (Reports, Community, The Apache Way, Conferences) and at the bottom missing ARIA menuitem labels. IMO (as explained [here](https://www.w3.org/TR/2019/NOTE-wai-aria-practices-1.1-20190814/examples/) or [here](https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/Roles/Navigation_Role)) it might be be better role=navigation instead of role menu. As multiple navigations are there a label (aria-label) might be used.

Start by reproducing the reported WAVE-tool findings on the ASF website and inspect the markup for the Reports, Community, The Apache Way, and Conferences links plus the bottom navigation. Done means the four empty-link findings are resolved and the navigation has appropriate labels or roles, with the WAVE results checked again.
