Missing win_arm64 wheels for aiohttp.

### Describe the bug

When trying to ``pip install`` in my project's folder to test for if I could install for ``win_arm64`` despite my CPU being amd64 I noticed that the resolution is impossible according to pip.

This command ``py -3.14.2 -m pip install --upgrade -r ./requirements.txt -t ./arm64-site-packages --platform win_arm64 --only-binary=:all:`` (using the Python Install Manager) with the following ``requirements.txt`` content:

```
discord.py
asqlite
aiohttp
```

results in the following:

ERROR: Cannot install -r ./requirements.txt (line 3) because these package versions have conflicting dependencies.

The conflict is caused by:
    aiohttp 3.6.2 depends on multidict<5.0 and >=4.5
    aiohttp 3.6.0 depends on multidict<5.0 and >=4.0

Additionally, some packages in these conflicts have no matching distributions available for your environment:
    multidict

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip to attempt to solve the dependency conflict

```

### To Reproduce

Install aiohttp for ``win_arm64`` using ``--platform`` in pip.

### Expected behavior

For pip to locate and install aiohttp and multidict from their arm64 windows wheels
