Update Corpus Metadata contents

The Impresso Datalab website retrieves the datasets collection from a private repository using the loader feature of AstroJS config (v5). However, the datset file is stored in a private repository. To access the private repository, you'll need to configure a GitHub fine-grained personal access token (PAT) and set it as a secret in this repository. In order to allow the GitHub Actions workflow to build the Docker image for the website, you need to:

1. Create a Fine-Grained Personal Access Token (PAT) with the following scopes:

    Repository: Read access to the private repository containing the datasets **and** access to repository ontents and commits.
   

2. Add the PAT as a Secret in your repository:

    Go to Settings > Secrets and variables > Actions.
    Click New repository secret.
    Name the secret: PAT_GITHUB_TOKEN.
    Paste the token as the value.
   

Example of configuration on our YAML GitHub action file

Mke sure that the dockerfile gets the right value on its GITHUB_TOKEN args
