[java] TooFewBranchesForASwitchStatement should consider Switch Expressions

[adangel]

Affects PMD Version: 7.6.0

Rule: TooFewBranchesForASwitchStatement

Description:
The rule currently only checks Switch Statements, but should also check Switch Expressions.

Therefore, the rule should be renamed to TooFewBranchesForSwitch (remove the statement part)

Code Sample demonstrating the issue:

public class DumbSwitch {
    public String foo(int i) {
        return switch (i) {  // violation expected here
            case 0:
            {
                yield "I am a fish.";
            }
        };
    }
}

Expected outcome:

PMD should report a violation at line ..., but doesn't. This is a false-negative.
