### Godot version

4.1.stable.flathub

### System information

Ubuntu 22

### Issue description

I'm converting my project and just caught the version 4.0 in _`"to work in Godot 4.0"`_ instead of current version. I'm not sure if it's intended but I feel like it would make more sense to have current version or just 4.x

### Steps to reproduce

Try converting a project to Godot 4 from Godot 3

### Minimal reproduction project

Default Godot 3 project opened with Godot 4
GDScriptTokenizer::Token::Type op_type = previous.type;
	UnaryOpNode *operation = alloc_node<UnaryOpNode>();
	switch (op_type) {
		case GDScriptTokenizer::Token::MINUS:
			operation->operation = UnaryOpNode::OP_NEGATIVE;
			operation->variant_op = Variant::OP_NEGATE;
			operation->operand = parse_precedence(PREC_SIGN, false);
			if (operation->operand == nullptr) {
				push_error(R"(Expected expression after "-" operator.)");
			}
			break;
		case GDScriptTokenizer::Token::PLUS:
			operation->operation = UnaryOpNode::OP_POSITIVE;
			operation->variant_op = Variant::OP_POSITIVE;
			operation->operand = parse_precedence(PREC_SIGN, false);
			if (operation->operand == nullptr) {
				push_error(R"(Expected expression after "+" operator.)");
			}
			break;
		case GDScriptTokenizer::Token::TILDE:
			operation->operation = UnaryOpNode::OP_COMPLEMENT;
			operation->variant_op = Variant::OP_BIT_NEGATE;
			operation->operand = parse_precedence(PREC_BIT_NOT, false);
			if (operation->operand == nullptr) {
				push_error(R"(Expected expression after "~" operator.)");
			}
			break;
