[groovyscripting] Update Groovy to 4.0.9 and support slurpers (#14499)

Updates Groovy from 4.0.7 to 4.0.9.

For release notes, see:

https://groovy-lang.org/changelogs/changelog-4.0.8.html
https://groovy-lang.org/changelogs/changelog-4.0.9.html

Adds dependencies and service loader config so JSON, XML and YAML can be more easily parsed using the JsonSlurper, XmlSlurper and YamlSlurper.
