Integrate async project

- docs are moved to grails-doc repo
- old async github workflows & associated config removed
- async & events split into separate directories
- shared example project now lives in grails-test-examples
- remove test and example projects from the bom
- fix async / events in the bom now that they're in grails-core
- change the build action to not fail fast so we can identify which version of java is failing
