Update dependencies and change SBA port

[TimHess]

• Update Steeltoe images to use Spring Boot 3.3.6.
• fixes Update Spring Boot Admin image #37.
• Change the Spring Boot Admin server port to avoid conflict with Prometheus
  • I can't find a standard port for SBA and 9099 doesn't seem to be claimed by anything else
• Fix a couple initializr params and add another so we can drop version.patch files. fixes Some parameters passed to Initializr are wrong #39

These are currently the expected library versions (via Initializr):

ext {
  set('springBootAdminVersion', "3.3.6")
  set('springCloudVersion', "2023.0.3")
}

The springCloudVersion translates to 4.1.3 for Config Server and Eureka, which does not change with this PR.

Thanks. I've run a sanity check with our samples for discovery-first Eureka/ConfigServer and verified the log-level colors in SBA. Everything looks good.
