In expression (?(group)...) an appropriate re.error is now
raised if the group number refers to not defined group.

Previously it raised RuntimeError: invalid SRE code.

Closes #91700.

Sorry, @serhiy-storchaka, I could not cleanly backport this to 3.10 due to a conflict.
Please backport using cherry_picker on command line.
