Description

React will issue a warning in dev if you try to use pass innerHTML prop to a DOM element tag.

https://github.com/facebook/react/blob/85dcbf83/src/renderers/dom/shared/ReactDOMComponent.js#L182-L184

This should be easy enough to enforce for most cases with a linter rule.

Bad:

<div innerHTML='HTML' />

Good:

<div dangerouslySetInnerHTML={{ __html: 'HTML' }} />

Research direction
Examine existing ESLint rules in the plugin for patterns, then implement a rule that detects the innerHTML prop on DOM elements by checking JSX attribute names and element types. Reference the React source code for the warning message and conditions.
