springboot Springboot 2.3.0.M1

Springboot 2.3.0.M1 is not in maven therefor testing the current code base against it is unnesasary difficult.

We don't publish milestones to maven Central but to https://repo.spring.io/milestone

Thanks, @spencergibb.

@TLiese if you generate a project on start.spring.io and select 2.3.0.M1, the build (Maven or Gradle) will be automatically configured with the required repository.
