[Access] Add examples for ws conn usages

[Guitarheroua]

The WebSocket examples should be written in a language other than Go, ideally in JS.

The WebSocket examples should be divided into two types:

1. Basic templates that could be used as a skeleton for a WebSocket project. They should include a WebSocket connection, examples demonstrating key actions such as 'subscribe,' 'unsubscribe,' and 'listOfSubscription,' and a message handler to receive messages from various topics.
2. Real-life usage examples that illustrate small projects and possible ways to integrate WebSockets into a project. Similar to what was done, for instance, in the article https://medium.com/@thekrokcompany/how-to-use-flow-event-subscription-23992f445ed0

The WebSocket examples repo should be created in https://github.com/The-K-R-O-K organization

Speaking of 1, I added a skeleton of small examples here. I'll add more when everything is merged and I can test them against local net.

Regarding 2, we haven't come up with any good ideas yet, so we are postponing it as well.

Moving this one to Blocked till we finish with fixing/merging other PRs related to websockets
