fix: add some checks to deploy scripts (closes #246)

fix: add some checks to deploy scripts

the rsync command in the github actions runs --delete which clear the
current folder. if this runs in the wrong directory it should cause
problems. the deploy script should now check that variables are set
correctly before attempting to do the rsync
