fix: add /bin/sh to Dockerfile (#10)

Because

- `docker compose  up` from `instill-core` produces an error 

```sh
Error response from daemon: failed to create task for container: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: exec: "/bin/sh": stat /bin/sh: no such file or directory: unknown
make: *** [latest] Error 1
```

This commit

- Corrects `Dockerfile`. It had originally been copied from
`mgmt-backend` but then adjusted based on other services. This commit
reconciles the build strategy.
