✨(prefect) add local prefect base configuration

[jmaupetit]

Purpose

Add prefect to our stack to run and orchestrate data pipelines.

Proposal

• [x] add local development stack
• [x] add first deployment
• [x] add prefect.yaml configuration (for deployments)

It seems that we have cache-related issues with the CI. Will wait a bit before merging this. But all tests pass!
