net-im/py-punjab: mark BROKEN and set to expire

This port fails at runtime. If I run it with rc-script:
"""

File "/usr/local/lib/python3.11/site-packages/punjab/httpb.py", line 17, in
<module>
  import error

builtins.ModuleNotFoundError: No module named 'error'

Failed to load application: No module named 'error'

/usr/local/etc/rc.d/punjab: WARNING: failed to start punjab
"""

and if I run it directly with twistd punjab:
"""
builtins.TypeError: Class advice impossible in Python3. Use the @implementer
class decorator instead.
"""

There is no maintainer and last activity in project repo dated 6 years ago.

Prevent building of this package at cluster and set to expire in one month.
