[ MSCOSDU-1955] remove git sha from dag name
Current behavior
- CSV parser dag name is appended with Git sha of commit which lead to lot of duplicate dags in GLAB env.
Expected behavior
- This MR removes appended git sha from dag name, dag file name and in the docker image.
- This would help in standardizing dags workflows
