[REQ] Improve documentation for Gradle 8.0.2

[GoGoris]

Is your feature request related to a problem? Please describe.

The Gradle documentation is outdated for Gradle 8.

Describe the solution you'd like

Update the documentation to use the lazy tasks.register api instead of the deprecated methods.

def generateModelsTask = tasks.register('generateModels', GenerateTask) {
    generatorName = "java"
    inputSpec = "<inputSpec>"
    outputDir = "<outputDir>"
    modelPackage = "<package>"
    generateModelTests = false
    globalProperties.putAll([
            // force only the models
            apis    : "false",
            invokers: "false",
    ])
    configOptions.putAll([
            library             : "native",
            serializationLibrary: "jackson",
            dateLibrary         : "java8",
            useJakartaEe        : "true",
    ])
}

compileJava.dependsOn generateModelsTask
