Update aiohttp to last patch version 3.11.11

[obulat]

Fixes

This update might help address the memory leak problem. This PR is based on the Python update PR (#5327)

Description

Here's the summary from ChatGPT of why upgrading might help solve memory leak problems:

A critical bugfix that affects streaming downloads:

• Fixed Paused Connections on Streaming (#10169):
  There was a bug where connections used for streaming downloads could return to the pool in a paused state. Even though we don’t iterate over chunks manually, calling await upstream_response.content.read() in the thumbnail is still “streaming” under the hood. This could lead to connections remaining half-open, causing a buildup of idle connections and potentially leading to memory or resource leaks.

• Improved Keep-Alive and force_close Handling:
  In various 3.11.x patches, aiohttp improved how connections are reused and cleaned up (e.g. #9997, #10003). These changes help ensure connections won’t remain stuck in the pool if force_close or keep-alive logic isn’t handled properly.

By upgrading to aiohttp 3.11.11, we expect to see improved stability and fewer issues with unclosed or “paused” connections in our thumbnail service.

Very interesting context. Thanks for sharing! This looks good to me if you want to mark it as ready and deploy as well.
