Update man page for `docker create` to add `--rm` flag
Update man page for `docker create` to add `--rm` flag

The `--rm` flag has been part of the `docker create` and
related docs in `docs/reference/commandline/create.md`
already includes the `--rm` flag. However, man page
`man/docker-create.1.md` has not adds the `--rm` flag yet.

This fix adds the description of `--rm` flag to
`man/docker-create.1.md`
