Regex to check 42 hostname, reset script

[digiator42]

Validate possible 42 hostnames to check wether the student in 42 lab or not, no need for 42 lab question.

Added reset script to reset and cleanup Docker and fix "A JavaScript error occurred in the main process" (For opening docker only without installing Valgrind image)
