Incorrect Documentation for read Method

[AlexMubarakshin]

Hey!

I noticed an issue with the documentation for the read method.

In the provided example, the method field is used like this:

const res = await contractClient.read({
  method: 'counter',
  arguments: [],
});

However, it should be getter instead of method, like so:

const res = await contractClient.read({
  getter: 'counter',
  arguments: [],
});

Thanks!
