Updates to support groovy 4

[AngMits]

Fixes

• Parsing Groovy 4 switch statements.
• I have been facing issues with parsing switch statements after upgrading work-related projects to Groovy 4. The current state of the linter will throw a parser error if it encounters such a statement.
• Instead of adding exclusions for each case, adding support for the language would be a slightly better alternative.

Proposed Changes

• Update jars to their latest versions (commons)
• Update jars to support Groovy 4

Additional info ℹ️

• Although local tests are passing, and a trial run using the actions showed that nothing is broken, please request any changes that might be required or any other course of action.
• The added import in the CodeNarcServer was required, otherwise Groovy would throw an error.
• The update of the workflow file was done to check the workflows, otherwise, an error version would be thrown.

Just a quick note to say I've seen this and its on my list to look at.

I believe a minimal example could be useful here for testing. Instead of updating the description, I'm adding this working code snippet as a comment. More complex scenarios benefit from this syntax, but this should be sufficient, as it reflects a somewhat reasonable use of a Groovy class that features return statements.

class TestClass {

    enum TestStrings{
        ONE('One has been used'),
        TWO('Two has been used'),
        DEFAULT('Default string')
  
        String content
  
        TestStrings(String content) {
            this.content = content
        }

        String get() {
            content
        }
    }

    static String compareStrings(String testString) {
 
        String innerString = TestStrings.DEFAULT.get()

        switch (testString) {
            case 'one' -> {
                innerString = TestStrings.ONE.get()
                println(innerString)
            }
            case 'two' -> {
                innerString = TestStrings.TWO.get()
                println(innerString)
            }
           default -> println(innerString)
        }
        innerString
    }
}

assert TestClass.compareStrings() == TestClass.TestStrings.DEFAULT.get()
assert TestClass.compareStrings('one') == TestClass.TestStrings.ONE.get()
assert TestClass.compareStrings('two') == TestClass.TestStrings.TWO.get()

Looks like just an editor format change and then should be good to go.
