ARM64 dev support (#1863)

* chore(docker): improve repeat contributions workflow

* This change adds two new commands to gracefully stop and remove the Postgres and Clickhouse docker containers. To do so, it also gives them a recognizable name.

* Additionally, the Postgres container is updated to use a named volume for its data. This lower friction for repeat contributions where one would otherwise sign up and activate their accounts again and again each time.

* Apple M1 compatibility for local development

* Patch upgrade for Python to a version that is built without errors
* Use a new community image for clickhouse that's ARM64 compatible
* Update contribution docs

 ### Start the environment:
 
 1. Run both `make postgres` and `make clickhouse`.
+    1. If you are using Apple Silicon (any of the M1 or similar SoC variants), `make clickhouse-arm` offers a development-only substitute that will work on your local machine. Not intended for production.
 2. You can set up everything with `make install`, alternatively run each command separately:
     1. Run `mix deps.get`. This will download the required Elixir dependencies.
     2. Run `mix ecto.create`. This will create the required databases in both Postgres and Clickhouse.
