Allow customization of terminal commands

These lines are hardcoded:

devbox-scripts/openWt.mjs

Lines 103 to 106 in a5f3952

	const term1Command = `ssh ${devboxSsh} -t "sleep 3\\;cd /home/vagrant/projects/${relativeProjectPath}\\; bash --login"` // sleep 3: smartcd supporte mal d'être lancé deux fois en parallèle...
	const term2Command = `ssh ${devboxSsh} -t "cd /home/vagrant/projects/${relativeProjectPath}\\; bash --login"`
	const term3Command = `node mutagenStart.mjs ${path.basename(projectPath)}`
	const term4Command = `ssh ${devboxSsh} -t "sleep 6\\;cd /home/vagrant/projects/${relativeProjectPath}\\; bash --login"` // sleep 6: smartcd supporte mal d'être lancé deux fois en parallèle... Alors 3 fois...

It would be nice to expose, from the variables.default.mjs, a single method that gets the terminal commands to run.
It should take as params the command line parameters, and info about the devbox, and return an array of commands to run.

This way, the configuration could be overriden by the variables.mjs file
