Docker image doesn't support M1 chip

[robert-ngo]

We get this issue when pulling docker image evolvingweb/sitediff on a M1 chip.

latest: Pulling from evolvingweb/sitediff
no matching manifest for linux/arm64/v8 in the manifest list entries
Unable to pull Docker images: exit status 1 
Building project images...

Failed to start beneva: composeCmd failed to run 'COMPOSE_PROJECT_NAME=ddev-beneva docker-compose -f /Users/marien/Beneva/ssqca/.ddev/.ddev-docker-compose-full.yaml up -d', action='[up -d]', err='exit status 18', stdout='', stderr=' sitediff Pulling 
no matching manifest for linux/arm64/v8 in the manifest list entries'

Solution: revise CI script to support building multi-platform image.
