GitHub Actions CI (#2628)

* Add GitHub Actions CI

Configured to attempt builds with Java 8 and 11, plus a Java 17
build that is allowed to fail (since it currently is).

* Maven: remove prerequisite config

* Remove TravisCI config

* Maven: Update project version to 3.1.0.1-SNAPSHOT

* CI: add Windows and MacOS (JDK 8 and 11 only)

* CI: Make artifact names unique
