fix: Leaking yamux session after HTTP handler is closed (#329)

* fix: Leaking yamux session after HTTP handler is closed

Closes #317. The httptest server cancels the context after the connection
is closed, but if a connection takes a long time to close, the request
would never end. This applies a context to the entire listener that cancels
on test cleanup.

After discussion with @bryphe-coder, reducing the parallel limit on
Windows is likely to reduce failures as well.

* Switch to windows-2022 to improve decompression

* Invalidate cache on matrix OS
