refactor(deploy): parameterize git remote in deploy scripts

Replace hardcoded GIT_REMOTE variable with a function parameter so the
shared deploy library can push to either the production or test remote
from the same script. Rename push_to_server to push_to_remote and update
both deploy_web.sh and deploy_web_test.sh to pass the appropriate remote.
