Update docker images to reduce security vulnerabilities

[adthrasher]

This resolves 960 security vulnerabilities. Mainly by switching compatible images to an alpine base image. Other improvements include updating base OS versions and updating packages. There are 25 remaining security vulnerabilities, all of which are Low/Medium by Snyk (level documentation). All of the remaining vulnerabilities are in the util image (which uses Ubuntu 24.04). We do an apt-get upgrade in the image and I've skimmed most of the remaining vulnerabilities and they have no fixed version in 24.04. So the only "fix" would be to change to a different image that does not have those vulnerabilities.
