chore: silence git describe errors in Docker make deps (#2823)

Silences the errors from running `make deps` locally and in CI:

```
 => [auth 6/8] RUN make deps                                                                                                                                                  15.5s
 => => # fatal: not a git repository (or any of the parent directories): .git
 => => # fatal: not a git repository (or any of the parent directories): .git
 => => # fatal: not a git repository (or any of the parent directories): .git

 => => # fatal: not a git repository (or any of the parent directories): .git
 => => # fatal: not a git repository (or any of the parent directories): .git
```

These warnings are expected when `.git` does not exist.
