Description

It would be nice if invalid DOM element name is detectable. How about this rule?

Research direction
Review existing rules in the eslint plugin react repository to understand the pattern for rule implementation. Check the ESLint plugin API for creating custom rules, and examine the AST of JSX elements. Look at comments on the issue for any maintainer guidance on which invalid DOM elements to include (e.g., a list of valid HTML tags from the HTML spec). Consider referencing the 'no unknown property' rule for similar approach.
