[mod] drop support for Python releases older than 4 years (#5895)

The end-of-life (EOL) of a Python release is reached after 5 years, with the
last three years dedicated to security fixes. [1]

Unfortunately, this doesn't apply to common libraries (dependencies): bug fixes
are often only included in major releases, and minor releases with corresponding
security fixes are rarely offered.

To make matters worse, these dependencies often prematurely discontinue their
support for older Python releases (because, for example, they want/need to use
new Python features).

If we want to offer secure software, we are faced with the dilemma of either
supporting old Python releases and accepting that there are security bugs in the
dependencies, or ending support for older Python versions before the actual EOL
of the Python release.
