PyQt and PyQtWebEngine do not depend on versions of each other.

I have tested, and a simple PyQtWebEngine based application works for me
and can load web pages fine, with PyQt 5.15 and PyQtWebEngine 5.14 (as
available right now in testing).

The autopkgtest also passed with these versions, though it only tries to
import modules and does not check if they actually work:

Maybe this is an issue in calibre, but hard to tell without a stack trace.
