Thanks for the PR!

The API documentation is auto-generated from JSDoc, so you need to fix it here:

gutenberg/packages/block-editor/src/components/block-list/use-block-props/index.js

Lines 52 to 58 in 720522f

	* const blockProps = useBlockProps(
	* className: 'my-custom-class',
	* style: {
	* color: '#222222',
	* backgroundColor: '#eeeeee'
	* }
	* )

After making changes, run npm run docs:build. Then commit and push those changes.
