Lexical version: v0.33.1 (but should also exist in latest 0.35)

Steps To Reproduce

1. Put cursor into a text field but don't select anything
2. Trigger a copy (i.e. cmd+c on mac)

The current behavior

An empty string is copied into the clipboard

The expected behavior

Clipboard is not updated. Should not be able to copy "nothing".

Offending code is likely here:

It only checks if selection is null, but it should also check if the selection is "empty" (i.e. isCollapsed)
