context.use does not return a context object

[avgdev]

docker.context.create returns a context object which can be later used in a DockerClient

context = docker.context.create(
                    context, 
                    docker=DockerContextConfig(host=base_url)
                ) 

print(type(context))
<class 'python_on_whales.components.context.cli_wrapper.Context'>

However if the context already exists a DockerException is thrown:

context = docker.context.create(
                    context, 
                    docker=DockerContextConfig(host=base_url)
                ) 

python_on_whales.exceptions.DockerException: The docker command executed was `/.cache/python-on-whales/docker-cli/20.10.5/docker context create --docker host=ssh://root@192.168.64.11,skip-tls-verify=False 192.168.64.11`.
It returned with code 1
The content of stdout is ''
The content of stderr is 'context "192.168.64.11" already exists

Calling docker.context.use("192.168.64.11") only switches to the context but does not return a context object making it very difficult to create a DockerClient with a context.

I think a workaround would be to use docker.context.inspect() to get the Context object, which is itself a context manager. But indeed it would be nice if the context could be returned with docker.context.use(). I'm open to a pull request to return the object.
