Workaround for excessive Checkstyle output fails for Gradle 7

[AdamCarroll]

The workaround to stop Checkstyle from producing exceesive logging (#11) fails under Gradle 7.

As a temporary measure, I've commented it out:

VocabHunter/build.gradle

Lines 65 to 68 in 749432e

	// TODO Restore this for Gradle 7.0
	// [checkstyleMain, checkstyleTest].each { task ->
	// task.logging.setLevel(LogLevel.LIFECYCLE)
	// }

For the record, here's the error:

$ ./gradlew clean build
Starting a Gradle Daemon, 1 busy Daemon could not be reused, use --status for details

FAILURE: Build failed with an exception.

* Where:
Build file '/Users/adam/Documents/IntelliJ/VocabHunter/build.gradle' line: 67

* What went wrong:
A problem occurred evaluating root project 'vocabhunter'.
> No signature of method: org.gradle.internal.logging.services.DefaultLoggingManager.setLevel() is applicable for argument types: (org.gradle.api.logging.LogLevel) values: [LIFECYCLE]
  Possible solutions: getLevel()

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

I've removed the commented out code to clean things up ready for the release
