[victorskl]

• Replaced drf_yasg with drf_spectacular
• Removed version pinning as skel template

This shall tame few recurring alerts related to skel in https:/umccr/orcabus/security/dependabot for good.

I think you will also need to add the pagination schema in the pagination.py that match to the get_paginated_response function.

    def get_paginated_response_schema(self, schema):
        return {
            "type": "object",
            'required': ['links', 'pagination', 'results'],
            "properties": {
                "links": {
                    "type": "object",
                    "properties": {
                        "next": {"type": "string", "format": "uri", "nullable": True,
                                 'example': 'http://api.example.org/accounts/?{page_query_param}=4'.format(
                                     page_query_param=self.page_query_param)},
                        "previous": {"type": "string", "format": "uri", "nullable": True,
                                     'example': 'http://api.example.org/accounts/?{page_query_param}=2'.format(
                                         page_query_param=self.page_query_param)},
                    },
                },
                "pagination": {
                    "type": "object",
                    "properties": {
                        PaginationConstant.COUNT: {"type": "integer"},
                        PaginationConstant.PAGE: {"type": "integer"},
                        PaginationConstant.ROWS_PER_PAGE: {"type": "integer"},
                    },
                },
                "results": schema
            },
        }
