Place the openapi deprecation tag directly under parameters

[mokshasoft]

When creating an openapi handler via reitit.openapi/create-openapi-handler the parameter deprecation tags are put under the schema tag, not directly under the parameters tag.

https://swagger.io/docs/specification/v3_0/describing-parameters/#deprecated-parameters

The openapi.json generated without this fix:

          {
            "in": "query",
            "name": "include-legacy-information",
            "required": false,
            "schema": {
              "deprecated": true
            },
          },

The openapi.json generated with this fix:

          {
            "in": "query",
            "name": "include-legacy-information",
            "required": false,
            "schema": {},
            "deprecated": true
          },

I was able to run these tests, that passed:
./scripts/test.sh clj
but not these, that failed for an unrelated reason:
./scripts/test.sh cljs
