Bug Description

In the following example, async_without_await suggest to remove async from init method, but it causes an error.

actor A {
    init() async {
        foo()
    }

    func foo() {}
}

This is only for actor as we can write without await, so it doesn't affect other data types.

Mention the command or other SwiftLint integration method that caused the issue. Include stack traces or command output.

$ swiftlint lint
