Describe the bug
Cookies are usually defined as key value pairs that follow a syntax as described by the MDN spec. However, generating code with the python generator for openapi-generator formats cookies in a different manner, mainly without the equal sign. This is also written in the auto-generated Configuration.py:

conf = openapi_client.Configuration(
 api_key={'cookieAuth': 'abc123'}
 api_key_prefix={'cookieAuth': 'JSESSIONID'}
)
 The following cookie will be added to the HTTP request:
 Cookie: JSESSIONID abc123

I assume this must be a bug since this does not follow the official MDN spec. If not, it might make sense to adjust the auto-generated comments since it is very easy to miss this issue.

OpenAPI Spec File
Unfortunately, I'm missing a non-local server to give a generic file but this should be a valid file for a generic health endpoint

/health:
 get:
