### What changes were proposed in this pull request?
This PR allows `bin/spark-submit --version` to show the correct information while the previous versions, which were created by `dev/create-release/do-release-docker.sh`, show incorrect information.
There are two root causes to show incorrect information:
1. Did not pass `USER` environment variable to the docker container
1. Did not keep `.git` directory in the work directory
### Why are the changes needed?
The information is missing while the previous versions show the correct information.
### Does this PR introduce any user-facing change?
Yes, the following is the console output in branch-2.3
```
$ bin/spark-submit --version
