chore: avoid anyio >= 4 for the moment

The 'policy' parameter is not supported anymore, and finding the right
workaround is tricky, especially because it's only needed for Windows,
and because anyio 4 doesn't support Python 3.7, so we would need to
support both the versions.

When we will drop Python 3.7 support it will be easier move to anyio >= 4.
