Minor Changes in the docker build command

[vaghawan]

Looks like the docker build command that was provided earlier should have been for the earlier version of Dockers, I'm using Docker version 19.03.8 and copying the above command doesn't work. Since in the newer version of docker, the --build-arg needs to be added separately for each param.

Thanks for the PR.
Could you update all the existing commands to use the new syntax everywhere?
There is no need to explain the difference as the new syntax is supported by previous versions, so we can just use a syntax which maximize compatibility.
