[Doc][Python] Ensure that ipc/io documentation uses context managers instead of manually closing streams #29139
Description
At the moment, in many places we are not closing or manually invoking .close() over resources that could deal automatically with it through context managers. We should replace those manual usages of .close() with context managers in the documentation so that we get users used to go for the more robust solution that doesn't require dedicated exception handling and remembering to close things.
