Schema in Package.xml prevents writing rosbag

[SegfaultCreator]

Description

XML Schema reference in /opt/ros/jazzy/share/rosbag2_storage_mcap/Package.xml prevents from writing Rosbag

Expected Behavior

Using ros galactic, we could write data into a rosbag as follows:

rosbag2_cpp::Writer rosWriter;

rosWriter.open(file.toStdString());

std_msgs::msg::String testmsg;
testmsg.data = "test";

rosWriter.write(testmsg, "TestMsg", rclcpp::Time(0));    

Actual Behavior

Executing the same code in ros jazzy leads to the following errors

[ERROR] [1736858572.767223751] [pluginlib.ClassLoader]: Could not find a root element for package manifest at /opt/ros/jazzy/share/rosbag2_storage_mcap/package.xml.

Further actions taken to track down the root cause

1. Commenting out this XML Schema reference in the storage_mcap/package.xml fixes the issue:
   <?xml-model href="http://download.ros.org/schema/package_format3.xsd" schematypens="http://www.w3.org/2001/XMLSchema"?>
2. The issue persists when downloading the schema and referencing the local schema.
3. XML is valid using xmllint
