Dockerize Local Development

[rush42]

This PR dockerizes the local development.

Notable changes:

• introduce build stages
• upgrade debian from bullseye to bookworm
• .env is used in local development

After this it is required to copy the content of the .env.example file to .env. The devolopment bundle can then be started with docker compose up.

I've checked out the branch and run:

cp .env.local .env
docker compose up

What I get is:

WARN[0000] The "GITHUB_SHA" variable is not set. Defaulting to a blank string. 
WARN[0000] The "TRAEFIK_HOST" variable is not set. Defaulting to a blank string. 
WARN[0000] The "TRAEFIK_HOST" variable is not set. Defaulting to a blank string. 
network processing_app_bridge declared as external, but could not be found

And what problem is this PR going to solve? Which ticket?

Thanks for the feedback! I get the warnings as well, the network bridge error however is new to me. Which version of docker are you using ?

For me, I cannot reproduce your error.
