Docker run command appears to be incorrect

[anthonymunene]

The README states to run via docker using the command
$ docker run -it --rm webpagetest-api -k YOURAPIKEY test https://docs.webpagetest.org/api/integrations/

when it should be

$ docker run -it --rm webpagetest-api test -k YOURAPIKEY https://docs.webpagetest.org/api/integrations/
