In this PR:
- Let the `<NavigationDrawerItem />` component render a `<button>` by
default instead of a `<div>`
- Replace `<div>` by `<span>` inside the `<NavigationDrawerItem />` as
`<button>` and `<a>` HTML elements only accept [_phrasing
content_](https://developer.mozilla.org/en-US/docs/Web/HTML/Content_categories#phrasing_content).
- Fix layout issue: the keyboard icon wasn't put on the right of the
button, I put it back
Fixes#7575
