Update `eth-json-rpc-middleware` to v9.0.1 (#16096)

This update includes fixes for our `block-ref` and `retry-on-empty` middleware. The `block-ref` middleware resolves the block reference `latest` to a specific block number, the latest one we are aware of. This is meant to protect against situations where the network gives inconsistent answers for what the latest block number is due to some nodes being out-of-sync with each other (this was a frequent problem years ago with Infura). It was broken in that the `latest` resolution was failing, and we were submitting an additional redundant request to Infura for each request. The `retry-on-empty` middleware is meant to retry certain methods when they return an empty response. This was also meant to deal with network synchronization issues that were more common years ago. This middleware works by making a "child" request over and over until either a retry limit is reached, or a non-empty response is received. It was broken in that the final response recieved was thrown away, so it's as though the middleware was not used. Except that it did result in additional redundant network requests. As a result of this update we should see that the extension is more resilient to certain network synchronization issues. But this is difficult to test, and these issues may not happen in production anymore today. We should see a reduction in requests to Infura as well. This should be easier to test.
