### 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
if (p_builtin) {
		return p_str.replace("\"", "\\\"");
	} else {
		return p_str;
	}
}
void ProjectConverter3To4::rename_gdscript_keywords(Vector<SourceLine> &source_lines, const RegExContainer &reg_container, bool builtin) {
	static String error_message = "The master and mastersync rpc behavior is not officially supported anymore. Try using another keyword or making custom logic using get_multiplayer().get_remote_sender_id()\n";
	for (SourceLine &source_line : source_lines) {
		if (source_line.is_comment) {
			continue;
		}
		String &line = source_line.line;
		if (uint64_t(line.length()) <= maximum_line_length) {
			if (line.contains("export")) {
				line = reg_container.keyword_gdscript_export_single.sub(line, "@export", true);
			}
			if (line.contains("export")) {
				line = reg_container.keyword_gdscript_export_mutli.sub(line, "$1@export", true);
