fix: unexpected event triggered when using ReactEditor.focus

[WindRunnerMax]

Description
When opening the document for the first time, using ReactEditor.focus to focus on the document unexpectedly triggers the onValueChange event, and there will also be an additional onChange event triggered.

Issue
Fixes: #5672

Example
The debug code is shown below, and the autoFocus property of Editable is turned off.

slate/site/examples/richtext.tsx

Lines 30 to 50 in 631a911

	// DEBUG: reproduce the problem env
	useMemo(() => {
	// @ts-expect-error debug
	window.editor = editor
	// @ts-expect-error debug
	window.ReactEditor = ReactEditor
	const { apply } = editor
	editor.apply = operation => {
	console.log('OnApply', operation)
	apply(operation)
	}
	}, [editor])
	return (
	<Slate
	editor={editor}
	initialValue={initialValue}
	onChange={(...args) => console.log('OnChange', ...args)}
	onValueChange={(...args) => console.log('OnValueChange', ...args)}
	onSelectionChange={(...args) => console.log('OnSelectionChange', ...args)}
	>

The effect when calling ReactEditor.focus is shown in the image, where you can see the unexpected event triggers.

Context

Actually, calling onChange in ReactEditor.focus isn't necessary. If needed, Transforms.select will handle triggering the event.

Thanks @WindRunnerMax . I'm going to approve and land this, but it's possible I'm forgetting a reason why that onChange call was in there. If there was a valid reason we may need to revert, we'll see!

@dylans If necessary, I am more than willing to rectify or assist in reverting this issue again and add the corresponding unit tests. 😄
