This commit reworks the CI pipeline to remove the use of Bintray for publishing to Maven Central. In its place it adds a new publishToCentral command to the release scripts. This command can be used to publish a directory tree of artifacts to the Maven Central gateway hosted by Sonatype. Publishing consists of 4 steps: 1. Create the staging repository 2. Deploy artifacts to the repository 3. Close the repository 4. Release the repository The command requires 3 arguments: 1. The type of release being performed 2. Location of a build info JSON file that describes the release that is to be deployed 3. Root of a directory structure, in Maven repository layout, that contains the artifacts to be deployed Closes gh-25107
