chore: updating CICD to support java server sdk package (#19)

This PR copies existing java-server-sdk code from the public repo and
takes the same approach as other migrated packages.

I made a separate commit for the code copy to make that easier to
verify. All code in lib/sdk/server should be identical to the [existing
repo ](https://github.com/launchdarkly/java-server-sdk)with no changes
intended except for release-please annotations put on
[Version.java](https://github.com/launchdarkly/java-core/pull/19/files#diff-880b7c7410f8d25590e54584048633f4068b855561e85ca77ea767b7514bb82f).
Please check them carefully.
