### 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
const String description = cf->get_value("application", "config/description", "");
	const PackedStringArray tags = cf->get_value("application", "config/tags", PackedStringArray());
	const String icon = cf->get_value("application", "config/icon", "");
	const String main_scene = cf->get_value("application", "run/main_scene", "");
	PackedStringArray project_features = cf->get_value("application", "config/features", PackedStringArray());
	PackedStringArray unsupported_features = ProjectSettings::get_unsupported_features(project_features);
	uint64_t last_eded = 0;
	if (cf_err == OK) {
		// The modification date marks the date the project was last eded.
		// This is because the `project.godot` file will always be modified
		// when eding a project (but not when running ).
		last_eded = FileAccess::get_modified_time(conf);
		String fscache = p_path.path_join(".fscache");
		if (FileAccess::exists(fscache)) {
			uint64_t cache_modified = FileAccess::get_modified_time(fscache);
			if (cache_modified > last_eded) {
				last_eded = cache_modified;
			}
		}
	} else {
		grayed = true;
		missing = true;
		print_line("Project is missing: " + conf);
	}
	for (const String &tag : tags) {
		ProjectManager::get_singleton()->add_new_tag(tag);
	}
	return Item(project_name, description, tags, p_path, icon, main_scene, unsupported_features, last_eded, p_favore, grayed, missing, config_version);
