# This GitHub Actions workflow automates the process of
# publishing dataset collections to a staging environment
# It is triggered by a pull request to the main branch
# that modifies any files within the ingestion-data/dataset-config/ directory
# The workflow includes steps to
#   - publish the datasets,
#   - constantly updates the status of the workflow in the PR comment
