(#236) Enable python module stream on EL8

[yachub]

Pull Request (PR) description

My apologies on missing this. In testing https://github.com/voxpupuli/puppet-letsencrypt/pull/254 I had manually enable the python36 module stream at some point before hand, but after running on a fresh install I realized certbot requires this module stream to be enabled per:

Error: Execution of '/bin/dnf -d 0 -e 1 -y install certbot' returned 1: Error:
 Problem: package certbot-1.20.0-1.el8.noarch requires python3-certbot = 1.20.0-1.el8, but none of the providers can be installed
  - package python3-certbot-1.20.0-1.el8.noarch requires /usr/bin/python3.6, but none of the providers can be installed
  - conflicting requests
  - package python36-3.6.8-2.module_el8.3.0+6191+6b4b10ec.x86_64 is filtered out by modular filtering

@ekohl You are really on top of it :) I rebased to see what had changed, but to be honest I'm not sure if this is really of value anymore. I'm currently using the module on a RHEL 9 host now, and I don't think that I remember having to manually enable any streams ¯_(ツ)_/¯
