Downgrade aiohttp to 3.8.5

[frenck]

Proposed change

Reverts #101590 against our rc: Downgrade aiohttp back to 3.8.5
We can't do this via dev, as dev is currently on aiohttp 3.9.0b0.

The issue: Ingress not always working. However, when the cache in the browser is disabled, it does work.

CleanShot.2023-10-13.at.00.18.30-converted.mp4

☝️ Please note how ingress works with the dev tools (and cache disabled) open, but doesn't when dev tools are closed.

Confirmed on nightly by installing 3.8.5, which makes the issue go away. Also confirmed by @joostlek who could reproduce on 2023.10.2, and downgrading also solved it on his end.

As for nightly, it has the same issue. I keep nightly in a "broken" state right now (workaround disable cache). As it gives us a platform to debug this more.
