Create a Keyvault to hold this access token

This is optional and you can use an existing keyvault

#gh api repos/opencontainers/image-spec/contributors > /tmp/contributors.json
# cat /tmp/contributors.json | jq -r '.[] | @text "|  \(.login) | ![avatar](\(.avatar_url)) | "'

get_contributors()
{
    REPO=$1
    FILE_NAME=/tmp/contributors-$REPO.json
    gh api repos/opencontainers/$REPO/contributors > $FILE_NAME
    cat $FILE_NAME | jq -r '.[] | @text "|  \(.login) | ![avatar](\(.avatar_url)) | "'
