BAU — Small tweaks to POM and Dependabot config

• Use Dropwizard version property so we upgrade Dropwizard and
  Dropwizard Testing Support for JUnit 4.x in lockstep

• Use Testcontainers BOM

• Stop using EclipseLink version property because it’s only used in
  one place

• Remove unused Guice version property

• Tell Dependabot not to try to upgrade us to Guice 7.0.0, which
  migrates from Java EE to Jakarta EE and is never going to be a
  just-merge-it upgrade
