Additional style field in generated OpenAPI Yaml that fails validation

[ben-iron]

After updating to the current version, the generated OpenAPI yaml includes a style: null field like so:

      - name: id
        schema:
          type: string
          format: uuid
        in: path
        description: the description
        required: true
        deprecated: false
        explode: true
        style: null

(see style: null in the last line)
This is not OpenAPI conform, where it has to be one of form, simple, spaceDelimited, etc. I can't figure out how to disable this.

This seems to be introduced by #940

I also observe linting failures after update:

error oas3-schema "style" property must be string.
