### Godot version

v4.0.beta13.official [caacade56]

### System information

Windows 8.1

### Issue description

The `Unreachable code (statement after return) in function 'function_name()'` warning is given for functions that do not have unreachable code. The same code does not give this warning in v3.5.stable.official [991bb6ac7].

### Steps to reproduce

```
func warning(i: int) -> void:
  if i == 0:
    pass
  elif i == 1:
    return
  else:
    return
  print("yeah")
```

Removing either the `elif` or the `else` removes the warning.

### Minimal reproduction project

N/A; code in reproduction steps can be placed in any blank gdscript file to trigger the error.
void GDScriptParser::TreePrinter::print_expression(ExpressionNode *p_expression) {
	if (p_expression == nullptr) {
		push_text("<invalid expression>");
		return;
	}
	switch (p_expression->type) {
		case Node::ARRAY:
			print_array(static_cast<ArrayNode *>(p_expression));
			break;
		case Node::ASSIGNMENT:
			print_assignment(static_cast<AssignmentNode *>(p_expression));
			break;
		case Node::AWAIT:
			print_await(static_cast<AwaitNode *>(p_expression));
			break;
		case Node::BINARY_OPERATOR:
			print_binary_op(static_cast<BinaryOpNode *>(p_expression));
			break;
		case Node::CALL:
			print_call(static_cast<CallNode *>(p_expression));
			break;
		case Node::CAST:
			print_cast(static_cast<CastNode *>(p_expression));
			break;
		case Node::DICTIONARY:
			print_dictionary(static_cast<DictionaryNode *>(p_expression));
			break;
		case Node::GET_NODE:
			print_get_node(static_cast<GetNodeNode *>(p_expression));
			break;
