chore(bump): grpc-js to 1.9.11

[jokesterfr]

A lot of stability fixes happened on grpc-js recently, I just want to make sure the EventStore client is up to date with these fixes.

I'm experiencing frequent issues with Error: 14 UNAVAILABLE: Server Is Not Ready on ES 23.10, which I guess is related to socket exhaustion due to mis disconnection of the client. Frequently on the server side we have 0 connections in the $ES_URL/subscriptions/${ES_STREAM}/${ES_GROUP}/info API response, while the Node.js client states that it is still connected.

Probably related to:

• https://github.com/grpc/grpc-node/issues/2397
• https://github.com/grpc/grpc-node/issues/2502
