Pull latest images in the Jenkins pipeline

[nutjob4life]

🗒️ Summary

Merge this to update the Jenkins pipeline to forcibly pull the latest images mentioned in the Docker Composition during the "build" phase.

👉 Note: after merging, the Jenkins configuration for the Registry should have its branch specifier changed from */pull-latest back to */main.

⚙️ Test Data and/or Report

Before the fix:

$ hostname
pds-expo.jpl.nasa.gov
$ docker image ls | egrep 'registry-(api|loader).*latest'
nasapds/registry-loader                         latest              0c32984f641f   12 months ago   480MB
nasapds/registry-api-service                    latest              f456cc7e4de0   14 months ago   544MB

After the fix:

$ docker image ls | egrep 'registry-(api|loader).*latest'
nasapds/registry-api-service                    latest              57771be577f0   6 days ago      526MB
nasapds/registry-loader                         latest              41b9fbee7ac1   8 weeks ago     474MB

Further, see the Jenkins run log wherein the number of failed assertion has plummeted from double-digits to single-digits.
