Mayan requires python 3.9 or higher since version 4.4
As this currently seems not be reflected in the release documentation, nor in setup.py, I open this issue to address the topic. Mayans search backend depends on @functools.cache, which has been introduced with Python version 3.9. Therefore, running Mayan with older versions fails. I think this was introduced with Mayan v4.4 in 4933303b.
