errors: fix comparison in errors.Is()

The code operates compares two values of compile-time type `any`. The
common use case however is to compare an error from `client.Do()` to one
of the reference errors, for example:

    if errors.Is(err, errors.ErrNotFound) {
        ...
    }

However, due to how the reference errors are constructed, their error
codes are of runtime-type `errors.ErrorCode`, whereas anything that got
parsed from a JSON response by `gqlerrors` will always be of
runtime-type `string`. Hence, Go will consider the two instances not
equal at runtime. Here [1] is little playground example demonstrating
the behavior.

To fix it, simply cast the special error type to back to string before
putting it in the map.
