Styling: README should import only the class and method instead of entire module

[adriantam]

Currently, the (README file)[https://github.com/openfga/python-sdk/blob/main/README.md] suggests importing openfga_sdk as a whole. For example, we have import openfga_sdk.

This is contrary to best practice in that only the relevant classes/methods should be imported. Instead, we should do something like

from openfga_sdk import ClientConfiguration

This will also require updating the example so that it does not have the prefix openfga_sdk.

As an example,

import openfga_sdk
from openfga_sdk.client import OpenFgaClient


async def main():
    configuration = openfga_sdk.ClientConfiguration(
        api_scheme = OPENFGA_API_SCHEME, # optional, defaults to "https"
        api_host = OPENFGA_API_HOST, # required, define without the scheme (e.g. api.fga.example instead of https://api.fga.example)
        store_id = OPENFGA_STORE_ID, # optional, not needed when calling `CreateStore` or `ListStores`
        authorization_model_id = OPENFGA_AUTHORIZATION_MODEL_ID, # Optional, can be overridden per request
    )
    # Enter a context with an instance of the OpenFgaClient
    async with OpenFgaClient(configuration) as fga_client:
        api_response = await fga_client.read_authorization_models()
        await fga_client.close()

should become

from openfga_sdk import ClientConfiguration
from openfga_sdk.client import OpenFgaClient


async def main():
    configuration = ClientConfiguration(
        api_scheme = OPENFGA_API_SCHEME, # optional, defaults to "https"
        api_host = OPENFGA_API_HOST, # required, define without the scheme (e.g. api.fga.example instead of https://api.fga.example)
        store_id = OPENFGA_STORE_ID, # optional, not needed when calling `CreateStore` or `ListStores`
        authorization_model_id = OPENFGA_AUTHORIZATION_MODEL_ID, # Optional, can be overridden per request
    )
    # Enter a context with an instance of the OpenFgaClient
    async with OpenFgaClient(configuration) as fga_client:
        api_response = await fga_client.read_authorization_models()
        await fga_client.close()

Ideally, we will also fix the SDK generator so that newly generated python SDKs will have the corresponding changes. This is tracked as openfga/sdk-generator#126. However, if that is difficult to do, simply focusing on the Python SDK side https://github.com/openfga/python-sdk/blob/main/README.md will help us as well.
