Authenticate to the GitHub Container Registry

To authenticate to the Github Container Registry, follow these steps:

1. Generate a Personal Access Token: Navigate to the New personal access token (classic) page on GitHub and create a new token with the write:packages and delete:packages scopes.
2. Configure Your Environment: Save your personal access token and GitHub username as environment variables:

   export GITHUB_TOKEN=<YOUR_TOKEN>
   export GITHUB_USERNAME=<YOUR_TOKEN>
   

3. Log in to the Container Registry: Use the Docker CLI to log in to the GitHub Container Registry by piping your GitHub token as the password:

   echo $GITHUB_TOKEN | docker login ghcr.io -u $GITHUB_USERNAME --password-stdin
