Purpose

Add a code action to fix return type signature of functions when the return type mismatches.

Fixes #13509

Approach

Suggest a code action, base on the diagnostic error message.

Samples

Before code action:

function addTwoIntegers2(int a, int b) {
   return (100, "");
}

After code action:

function addTwoIntegers2(int a, int b) returns (int, string) {
   return (100, "");
}
