Cloning from Private Repo (Microsoft Team Foundation Server - TFS)

I am having an issue cloning a repo from TFS. When using the `docker run` command I'm faced with the following errors:

### The base of my command:
```bash
docker run -it --rm \
-v /tmp/envbuilder:/workspaces \
-e ENVBUILDER_GIT_URL=https://tfs.example.com/tfs/EXAMPLE_Git_Collection/CloudEngineering/_git/example-helloworld-app-code \
-e ENVBUILDER_INIT_SCRIPT=bash \
artifactory.example.com/docker-virtual/ghcr.io/coder/envbuilder
```

The next step I tried was adding the extra environment variable ENVBUILDER_SSL_CERT_BASE64=ACTUAL_BASE64_CERT

The next step I tried was adding the extra environment variable ENVBUILDER_GIT_USERNAME=$PAT_TOKEN

The next step I tried was adding the extra environment variable ENVBUILDER_GIT_USERNAME=$BASE64_PAT_TOKEN
#### authentication required again

The next step I tried was adding the extra environment variable ENVBUILDER_GIT_USERNAME=my_tfs_username and ENVBUILDER_GIT_PASSWORD=my_tfs_password
#### authentication required again
```bash

```

The next step I tried was adding the extra environment variable ENVBUILDER_GIT_USERNAME=oauth and ENVBUILDER_GIT_PASSWORD=$BASE64_PAT_TOKEN

This produced the authentication required error again
