### Godot version

4.0.beta13 (caacade56)

### System information

Windows 10

### Issue description

Seems like this was missed in #62011 and #70540. `@export_multiline` should also support the PackedStringArray datatype on top of Array[String] and Dictionary, but it doesn't, instead giving the error `"@export_multiline" annotation requires a variable of type "String" but type "PackedStringArray" was given instead.`

### Steps to reproduce

Create a PackedStringArray with the `@export_multiline` annotation.
```gdscript
@export_multiline var npc_dialog: PackedStringArray
```

### 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();
