What changes did you make? (Give an overview)

Updated omitLastInOneLineBlock option in the semi rule to apply to class static blocks.

/*eslint semi: ["error", "always", { "omitLastInOneLineBlock": true}] */

if (foo) { bar() } // ok

if (foo) { bar(); baz() } // ok

function f() { bar(); baz() } // ok

class C {
    foo() { bar(); baz() } // ok

    static { bar(); baz() } // should be ok, too
}

Everything else in this rule already worked well for class static blocks, I just added test cases to confirm.

Is there anything you'd like reviewers to focus on?
