Problem: GitHub is dropping Python 2.7 support from CI workflows

[replaceafill]

Expected behaviour

GitHub CI workflows pass in the Archivematica related repositories written in Python.

Current behaviour

The setup-python action used in many CI workflows will drop Python 2.7 support on June 19. And GitHub also plans to remove the python:2.7 Docker image from their CI runners.

This will affect the following repositories:

• https://github.com/artefactual/automation-tools
• https://github.com/artefactual/fixity
• https://github.com/artefactual-labs/agentarchives/
• https://github.com/artefactual-labs/amclient
• https://github.com/artefactual-labs/ammcpc/
• https://github.com/artefactual-labs/mets-reader-writer

Steps to reproduce

This is not happening yet, but at some point the CI workflows of these repositories will start failing in the jobs that test Python 2.7.

Your environment (version of Archivematica, operating system, other relevant details)

GitHub CI workflows of the mentioned repositories.
