Composer script "docker:build" fails on Windows

[frantisekhallo]

'cp' is not recognized as an internal or external command,
operable program or batch file.
Script cp .env.dist .env handling the build:env event returned with error code 1
Script @build:env was called via docker:build

it is because normally the command cp is not available at Ms Windows operation system, i wonder if this should be somehow specially handled for different operating systems
but as a temporal workaround at windows, one has to have installed some linux tools, cli tools
or change the scripts->build:env to contain the copy command instead of the cp command

Currently we have no plans to include direct windows support for the composer/docker scripts. We are open for pull request though.
