Error during Build Process of Docker image

[damare]

The "Prerequisites" section refers to the use of Python 3.8.10, but the project's Dockerfile fixes Python only to v3, leading to
an error during the build process of the Docker image:

...
lib/zoneinfo_module.c: In function ‘zoneinfo_fromutc’:
lib/zoneinfo_module.c:600:19: error: ‘_PyLong_One’ undeclared (first use in this function); did you mean
‘_PyLong_New’?
...

Using the python:3.8.10 base image in the Dockerfile, fixes that problem.
