setup: use old importlib_metadata version to fix kombu failing on python < 3.8
Many libraries use the importlib_metadata library as fallback when running on
Python versions older than 3.8 . For example setuptools when easy_install is
used for install the Kallithea console_scripts entrypoints in the bin folder.
The dependencies on importlib_metadata were indirect and without constrains on
version number.
The problem is that Celery uses Kombu, which (on Python < 3.8) uses
importlib_metadata in a way that is incompatible with importlib_metadata > 5.
Most obvious, building docs failed as:
Running Sphinx v5.1.1
Configuration error:
There is a programmable error in your configuration file:

AttributeError: 'EntryPoints' object has no attribute 'get'
That made readthedocs builds fail, when it in the default web configuration
used Python 3.7 .
Fixed by introducing an explicit dependency on importlib_metadata < 5.
