Escaping version format on docker version checker

[danielsuguimoto]

@fabriciojs @dbpolito I'm trying to fix the bug we faced with start command on a WSL2 environment. I haven't tested it because I don't have a Windows environment here, but I'm suspecting that the bug's cause is the single quote inside the command to format docker version output. But even if this pull request doesn't fix the bug, it would be nice to be merged because is more safe if we escape quoted args...and I have added new tests.
