Enhancement Request: Add option to isEmpty to consider whitespace as empty

[indi-rin]

Description

It would be helpful if there was a way to have editor.isEmpty return true if the editor contains only whitespaces. Maybe something like editor.isEmpty({ ignoreWhitespace: true }) to support considering whitespace empty in addition to the existing behavior.

Currently, we can't use editor.isEmpty and instead have to check and trim the content with editor.getText() && editor().getText().trim().length > 0. It's not a terrible workaround but it'd be nice if we were able to utilize the built-in feature!

Use Case

I want to use this feature for cases where we process user input if there is text in the editor differently from if there is no text in the editor, and we don't consider whitespace to be text that can be processed.

(Also, while checking to see if this behavior was supported, I came across this StackOverflow from a year ago of other people asking about the same thing.)

I would probably not have it be on the editor instance, but maybe as part of isNodeEmpty (which is what backs editor.isEmpty anyway).

I would be willing to accept a PR that adds to the second parameter ignoreWhitespace (default false) to this function https://github.com/ueberdosis/tiptap/blob/develop/packages/core/src/helpers/isNodeEmpty.ts

Thank you. We might consider such a contribution.
