Disable timeout for Docker image pull operations (#6391)
* Disable timeout for Docker image pull operations

The aiodocker migration introduced a regression where image pulls could
timeout during slow downloads. The session-level timeout (900s total)
was being applied to pull operations, but docker-py explicitly sets
timeout=None for pulls, allowing them to run indefinitely.

When aiodocker receives timeout=None, it converts it to
ClientTimeout(total=None), which aiohttp treats as "no timeout"
(returns TimerNoop instead of enforcing a timeout).

This fixes TimeoutError exceptions that could occur during installation
on systems with slow network connections or when pulling large images.
