### Godot version

v4.0.beta14.official [28a24639c]

### System information

MacOS 12.6.2

### Issue description

Beta 14 throws an error for custom `@icon`, e.g.
```
class_name StateMachine extends Node

@icon("res://assets/icons/state_machine.svg")
```
> Annotation "`@icon`" is not allowed in this level.

In beta 13 and before that worked fine.

### Steps to reproduce

1. Add a custom `@icon` in a custom node script.
2. Error message: Annotation "`@icon`" is not allowed in this level.

There are possibly other errors because a `class_name` node is now not recognized if extended by other classes, but they should resolve if `@icon` is removed.

### Minimal reproduction project

N/A
return suite;
}
GDScriptParser::Node *GDScriptParser::parse_statement() {
	Node *result = nullptr;
#ifdef DEBUG_ENABLED
	bool unreachable = current_suite->has_return && !current_suite->has_unreachable_code;
#endif
	bool is_annotation = false;
	switch (current.type) {
		case GDScriptTokenizer::Token::PASS:
			advance();
			result = alloc_node<PassNode>();
			complete_extents(result);
			end_statement(R"("pass")");
			break;
		case GDScriptTokenizer::Token::VAR:
			advance();
			result = parse_variable();
			break;
		case GDScriptTokenizer::Token::CONST:
			advance();
			result = parse_constant();
			break;
		case GDScriptTokenizer::Token::IF:
			advance();
			result = parse_if();
			break;
		case GDScriptTokenizer::Token::FOR:
			advance();
			result = parse_for();
