broken with python3.12

Description:

It seems like there is an error with hplip which was first reported on reddit:

hp-setup         
/sbin/hp-setup:82: SyntaxWarning: invalid escape sequence '\*'
  ("To specify the port on a multi-port JetDirect:", "--port=<port> (Valid values are 1\*, 2, and 3. \*default)", "option", False),
/sbin/hp-setup:86: SyntaxWarning: invalid escape sequence '\*'
  ("Type of queue(s) to install:", "-t<typelist> or --type=<typelist>. <typelist>: print*, fax\* (\*default) (-i mode only)", "option", False),
Traceback (most recent call last):

    ^^^^^^^^^^^^^^^^
AttributeError: 'ConfigParser' object has no attribute 'readfp'. Did you mean: 'read'?

I do not use the tools but wanted it to be properly reported regardless 😇
