Remove ENV variable from CustomersDot servers
Related to gitlab-org/customers-gitlab-com#2015 (closed)
After closing https://gitlab.com/gitlab-org/customers-gitlab-com/-/issues/1657 the ENV variable FINANCE_CC_EMAIL
is obsolete. It can be safely removed for the staging and production server (I think this is stored in the chef-vault).
