Artifact + Matrix - 9

Adding .env file which stores only docker image timestamp for the latest dockerhub e-mission-server image already pushed.

.env file overwritten in both types of trigger events - push and workflow_dispatch.

Added commit and push github actions as well for pushing latest changes to the .env file made via the workflow.

Lastly, docker-compose now also mentions the ENV variable name to be read from the .env file for the ARG value in the Dockerfile.

No changes required in the Dockerfiles.
