Add DCA and Schematic versions to footer of dashboard. (#564)

* WIP: Add DCA and Schematic versions to footer of dashboard.

* Get schematic version via api call

* Use schematic version from variable in global.R

* Add version as an env variable to docker container

* When building docker container, use the github ref as a build arg to note the version.

* Change version variable to DCA_VERSION

* Set DCA_VERSION env var to a variable in the global env

* Show DCA version from the env var

* Use GITHUB_REF_NAME env var to set version env var.

* specify github context for github_ref_name var

* Update github ref name to github.REF_NAME

* For clarity, set build arg to DCA_VERSION instead of TAG.

* Add DCA_VERSION env var to .Renviron so it is loaded as env var in shiny server.

* Make DCA_VERSION from docker build-arg an env var in the container. Then in dca_startup.sh, add the env var to Renviron

* Add error handling for schematic version api call
