Fix various issues with installation of CamCHILDMine

[martinburchell]

In the process of getting the 2022 FAIR TREATMENT (CamCHILDMine) demo working I ended up making these changes. In summary:

• New GitHub workflow for building the docker images with the default Biotestmine
• Remove obsolete version from docker compose YAML files
• Abort build.sh if any part of the script fails unexpectedly
• Store docker-compose defaults in .env file
• Reduce some complexity in build.sh when resolving environment variables
• Use wait-for-it to ensure the various containers are running (bundled in as there is no Alpine package)
• Do not try to copy malaria-data.tar.gz if it is not present
• Remove the duplicate call to gradlew cargoDeployRemote. In CamCHILDMine I've implemented the workaround described in Gradle needs to start or deploy a second time to serve webapp intermine#2162 (comment)
• Use named volumes in the local.docker-compose.yml. I've removed the parsing of the YAML file in mkdatadirs.sh as this seemed like a brittle approach and made this script runnable from anywhere.
• Sort out various permissions issues.

There was a bit of guesswork involved so I'd appreciate another set of eyes on this.
