fix(docker): nested dockerfile/chalk mark in /tmp/ folder for snap pe…

…rmissions

looks like docker when installed via snap cant access tmp files directly inside /tmp
but it can access them when they are nested inside another folder in /tmp

this is important as chalk passes chalkmark and Dockerfile in some cases via tmp files
and so it needs to write it to a place which will be accessible by docker
