Identify simpler way to keep Java, Gradle and Groovy versions the same

[jamesfredley]

Issue description

Java version:
.sdkmanrc
.github/workflows/release.yml
etc/bin/Dockerfile

Gradle version:
grails-forge/grails-forge-core/src/main/java/org/grails/forge/feature/build/gradle/templates/gradleWrapperProperties.rocker.raw
gradle.properties (gradleToolingApiVersion)
.sdkmanrc
gradle/wrapper/gradle-wrapper.properties
build-logic/gradle/wrapper/gradle-wrapper.properties
grails-forge/gradle/wrapper/gradle-wrapper.properties
grails-gradle/gradle/wrapper/gradle-wrapper.properties
grails-profiles/base/skeleton/gradle/wrapper/gradle-wrapper.properties
grails-profiles/profile/skeleton/gradle/wrapper/gradle-wrapper.properties

The wrapper jar and scripts also change and this requires updates to those files in many locations.

Groovy Version:
dependencies.gradle
grails-forge/gradle.properties (latest 3.0.x, currently)

Gradle 8.x.x includes Groovy 3.0.x and Gradle 9.x.x includes Groovy 4.0.x

We already have a bootstrap project that can copy / stage wrapper scripts, running this script should sync / replace the existing scripts which will synchronize all of these values. I believe we just change the value in .sdkamnrc & then run the bootstrap to update. The only areas not updated at that point are .github & the docker file.

I'd suggest as part of this ticket we load the wrapper version from .sdkmanrc using the gradle properties action.

For the docker file, we should extract the version into an argument & then check-in a bootstrap / wrapper script that passes the correct args to the docker file.
