# This script is using the GitHub CLI with the GraphQL API in order to retrieve
# releases. The reasons are:
# - using 'gh release list' does not return all the releases
# - using the API, directly or via GitHub CLI, is slow, produces a lot of 502
# errors, and is harder due to pagination.
# - using the GraphQL API directly is hard due to pagination.
# - using a library, such as graphql-python, is sightly harder than using the
# GitHub CLI (and still requires a GITHUB_TOKEN).
