### 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.
push_text("Constant ");
	print_identifier(p_constant->identifier);
	increase_indent();
	push_line();
	push_text("= ");
	if (p_constant->initializer == nullptr) {
		push_text("<missing value>");
	} else {
		print_expression(p_constant->initializer);
	}
	decrease_indent();
	push_line();
}
void GDScriptParser::TreePrinter::print_dictionary(DictionaryNode *p_dictionary) {
	push_line("{");
	increase_indent();
	for (int i = 0; i < p_dictionary->elements.size(); i++) {
		print_expression(p_dictionary->elements[i].key);
		if (p_dictionary->style == DictionaryNode::PYTHON_DICT) {
			push_text(" : ");
		} else {
			push_text(" = ");
		}
		print_expression(p_dictionary->elements[i].value);
		push_line(" ,");
	}
	decrease_indent();
	push_text("}");
