Accessibility errors in jdwp-protocol.html

Axe reports lots of accessibility errors in the generated jdwp-protocol.html file.

Many of them appear to stem from an initial single error on line 13

<ul role="navigation">

That is not a legal role for this element, and causes errors for subsequent <li> items to report errors for not being enclosed in a suitable list item.

If you really want to declare this as a navigation element, I suggest one of the following 2 approaches.

1. remove `role="navigation"` from `<ul>` and enclose the complete list in `<div role="navigation">...</div>`

2. remove `role="navigation"` from `<ul>` and enclose the complete list in `<nav>...</nav>`
