ApiImplicitParam not showing File param on swagger UI

Hi ubaidshahid 

I'm no Java expert.

OpenAPI v3 has changed the way it handles file uploads (via Multipart) away from `paramters` and into `requestBody`.

This example may help...

@Path("/files")
@Produces("application/json")
public class MultiPartFileResource {
    @POST
    @Path("/upload")
    @Consumes(MediaType.MULTIPART_FORM_DATA)
    public Response uploadFile(@FormDataParam("fileIdRenamed") final String fileId,
                               @Parameter(schema = @Schema(type = "string", format = "binary")) @FormDataParam("fileRenamed") final InputStream file) {
        return Response.status(200).entity("File  " + fileId + " has been uploaded").build();
    }
}
