Replace buildkite jdk version check w/GH action (elastic#17945)

* Replace buildkite jdk version check w/GH action

Previously a weekly buildkite job would check if there is a newer JDK available
than the one vendored in logstash. This job would fail until someone manually
updated the JDK version in the `versions.yml` file in logstash. This commit
reduces manual intervention by moving the responsibility to a GH action where
there are patterns for creating PRs back to logstash. The action should run
weekly and also be available in the actions UI. It is locked down with the same
permissions as the version bump action.

* Refactor to use updatecli

* Remove gradle task in favor of updatecli

* remove unused file

* Dynamically generate java version lookup

* make pipeline name unique'
