Bump the minimum required version of Docker and Docker API #6916
Description
Is there an existing issue for this?
- I have searched the existing issues
Is your feature request related to a problem?
Sometimes we see user reports of non-working DDEV, where the problem is that they are using a fairly old Docker.
Our current constraint:
ddev/pkg/dockerutil/dockerutils.go
Line 1836 in 7dea56f
Describe your solution
Bump it to something newer.
Docker supports Ubuntu Focal 20.04 (LTS)
https://docs.docker.com/engine/install/ubuntu/#os-requirements
The previous Ubuntu Bionic 18.04 has support up to Docker 24.0.2
https://download.docker.com/linux/ubuntu/dists/bionic/pool/stable/amd64/
Debian Bullseye 11 is supported too
https://docs.docker.com/engine/install/debian/#os-requirements
We have this optional check for healthcheck.start_interval that is supported from Docker v25+ in our code
Line 208 in 7dea56f
Docker API matrix

Additional context
I'm not sure which version we want to see minimal, I'm only sure that people had problems with early versions of 20.10+.
