SonarQube analyzer for Go language

There is a newer version: 1.24.0.3049

Why is this an issue?
The requirement for a final default clause is defensive programming. The clause should either take appropriate action, or contain a
suitable comment as to why no action is taken.
Noncompliant code example
switch tag { // Noncompliant - default case is missing
case 0, 1, 2, 3:
	foo()
case 4, 5, 6, 7:
	bar()
}

Compliant solution
switch tag {
case 0, 1, 2, 3:
	foo()
case 4, 5, 6, 7:
	bar()
default:
	qix()
}
