Feature Request: generateschema should parse query string parameters in Docstring

[rpaknahad]

Using DRF`s generateschema command, Docstring inline documentations are automatically parsed, but there is no way to add extra query parameters or document existing parameters inside that Docstring.
Here is an example:

@action(detail=False, methods=['post'])
def add(self, request):
  """
  Adds a new account
  parameters:
  - in: query
    name: service_id
    type: string
    required: true
    description: Identifier of the service
"""

This was added in #6898 which was part of 3.11

Duplicate of #7212. The discussion group is the best place to take this discussion and other usage questions. Thanks!
