pasteHandler doesn't work correctly for list items when their content is empty prior to pasting text.

Problem:

1. Create bullet/numbered/checklist item
2. Try to paste text into its content
3. List item gets replaced with paragraph (This happens when list item content is empty).

The following code solves the problem, but I don't if it is ideal:

pasteHandler: ({ event, editor, defaultPasteHandler }) => {
	const currentBlock = editor.getTextCursorPosition().block;
	const blockSpec = editor.schema.blockSchema[currentBlock.type];
	
	const hasInlineContent = blockSpec?.content === "inline";
	const isEmpty = !currentBlock.content || 
		(Array.isArray(currentBlock.content) && currentBlock.content.length === 0);
	
	if (hasInlineContent && isEmpty) {
		const plainText = event.clipboardData?.getData("text/plain");
		if (plainText) {
			editor.pasteText(plainText);
			return true;
		}
	}
	
	return defaultPasteHandler();
},

Thanks for trying to provide a fix, I think that what we need here is not to just attempt pasting the content as text, but instead allow the paste into the list item without replacing the list item. If the pasted content is a paragraph it is fine to ignore the surrounding paragraph, and paste just it's content into the editor. But, if the pasted content is something like a list item (or other block), then it should have the current behavior of just overriding the empty block with the new content (in an attempt to preserver that it was a list item)

@nperez0111 thank you very much for feedback. I realized that it fixes the issue for list item blocks but breaks pasting with formatting in general for other situations.
