* WIP: release footprint in the admin UI
* feat: show the commit ID and the date
* chore: change env optional to empty string
* fix: change the FOREM_BUILD_DATE to RELEASE_FOOTPRINT
* feat: add Not Available as a last option
* test: last deployed time and latest commit id
* feat: update the way we change the env variable!
