docs, man: remove confusing example for "--isolation"

This snippet was added in [38ec5d8][1]. The intent was to indicate that an empty value is equivalent to passing "default" as value. However, passing the `--isolation` flag _without a value_ (i.e., no `=` specified) will fail in many cases, as any string after it will be parsed as value (e.g. `docker run --isolation busybox` would consider `busybox` as value). This patch removes these lines as they add more confusion than addressing.
