fix: add Python as it has been in use in various repos.

[artsyjian]

In recent discussions around an Opstools PR, we noticed that the Tech Radar has no entry for Python. It seems we should add such an entry, because there are significant repositories with Python code, Hokusai/Motion/Zenith being the main ones.

The description field for the entry is left blank, to be filled in based on discussion in this PR, therefore, the PR is tagged Draft.

Good call. I need to add Airflow and AWS Batch as platforms as well, they appear to be missing. For a description I would suggest:

For ETL, Analytics and ML workloads we use Python as a data engineering standard.

We should definitely clarify its "adopt" status for data purposes. I like the description @cavvia suggests.

For infrastructure tooling (starting with hokusai and opstools/ops-util), it feels more incidental. I think @izakp chose it since it was most familiar and had strong library support, which are the same motivations the org usually has around ruby. I'd argue we have more broad internal knowledge of maintaining and deploying ruby as well, so I'd want that to be considered before starting new python projects in non-data areas.
