[ListItem] Using button prop forces an invalid nesting of list items

[heidi-jungel]

When using the component passing a prop, it produces invalid nesting as it converts this from an <li> to a <div> with a button role.

• The issue is present in the latest release.
• I have searched the issues of this repository and believe that this is not a duplicate.

Current Behavior 😯

This causes a lot of problems for users of assistive technologies.
Ideally, it should be a single default button (to hold keyboard internation) nested in a singleli element.

Expected Behavior 🤔

Should be
<li...><button....>...
