Running on Windows from different drive than C:\

- Running from drive different than your `%USERPROFILE%` one (typically `C:`), for example on `D:\` would try to read `\Users\\.docker\config.json` (I've replaced my username with `` below)

- Workaround
* Not best workaround, but setting `DOCKER_CONFIG` to some value in `.bazelrc` _"fixes"_ this

common --repo_env=DOCKER_CONFIG=does_not_matter

* It reports now:

WARNING: Could not find the `$HOME/.docker/config.json` and `$XDG_RUNTIME_DIR/containers/auth.json` file. Running one of `podman login`, `docker login`, `crane login` may help.

Start by reading oci/private/pull.bzl, especially _get_auth_config_path and _create_downloader, using the reported Windows error as the reproduction context. Verify how the Docker config path is formed when the project runs from a drive other than C:. Done means the path no longer incorrectly resolves to \Users\... and the workaround setting DOCKER_CONFIG is unnecessary.
