Add Graph API version to base URI

[Ndiritu]

Is your feature request related to a problem? Please describe the problem.

Currently, the base URI only contains the national cloud host, meaning each request needs a Graph API version prefix:

$httpClient = GraphClientFactory::createWithConfig($config);
$response = $httpClient->get("/v1.0/me");

Current workaround is to override the base_uri via config:

$httpClient = GraphClientFactory::createWithConfig(['base_uri' => NationalCloud::Global + "/v1.0"]);
$response = $httpClient->get("/me");

This would be a breaking change.

Describe the solution you'd like.

Support setting the Graph API version via the factory & default to v1.0
(With default v1.0)

$httpClient = GraphClientFactory::create();
$response = $httpClient->get("/me");

Or to change to beta

$httpClient = GraphClientFactory::setApiVersion('beta')::create();
$response = $httpClient->get("/me");

Additional context?

This does not necessarily have to be a breaking change.
We could always add an overload that takes in version parameter or add a property to the config object.

Good catch, yes we can add a version parameter that defaults to an empty string.
The config object ideally maps to a Guzzle request options object.
