Remove Python 3.8 from the testing matrix

Python 3.8 support officially ended on October 7th, 2024. Recommendation
is that consumers of the library should upgrade their environment to
Python 3.9+.
Initially this commit removes Python 3.8 from the CI testing matrix.
In a future change, we might want to bump python_requires to require
Python 3.9 as the minimal version
