RE: Apache Grails on Apache Groovy 5

[James Fredley]

The two Grails PRs focused on Groovy 5 and Groovy 6 have been 
extensively updated based on the latest snapshots and the substantial 
work on the Groovy 5(GROOVY_5_0_X) and 6 (master) branches.

Groovy 5: https://github.com/apache/grails-core/pull/15557
Groovy 6 (canary): https://github.com/apache/grails-core/pull/15558
