Small naming issues in Cortex4py usage.md examples

[simonspgn]

Just to note that I have noticed two small typing errors while going through Cortex4py documentation.

1. In the example showing how to manipulate organizations as orgadmin change 'status','Active' to 'status','Ok':

From

users = api.organizations.get_users(org.id, Eq('status', 'Active'), range='0-5', sort='-createdAt')

To

users = api.organizations.get_users(org.id, Eq('status', 'Ok'), range='0-5', sort='-createdAt')

Otherwise active users won't be shown.

2. In the example showing how to manipulate analyzers, to enable an analyzer change
   Change the "api_key" parameter in configuration to "key":

From

analyzer = api.analyzers.enable('Test_1_0', {
  "configuration": {
    "api_key": "XXXXXXXXXXXXXx",
    "proxy_http": "http://localhost:9999",
    "proxy_https": "http://localhost:9999",
    "auto_extract_artifacts": False,
    "check_tlp": True,
    "max_tlp": 2
  }

To

analyzer = api.analyzers.enable('Test_1_0', {
  "configuration": {
    "key": "XXXXXXXXXXXXXx",
    "proxy_http": "http://localhost:9999",
    "proxy_https": "http://localhost:9999",
    "auto_extract_artifacts": False,
    "check_tlp": True,
    "max_tlp": 2
  }

Otherwise "Invalid input Excetion" will be returned.

Nothing big at all, just small little typing errors which might not necessarily be easy to notice for everyone as they took me quite some time to figure out! Hope this helps :)
