Aggregate the app descriptors of each channel into listings/apps.json and listings/apps-contrib.json in the repository, with a Scala CLI script (.github/scripts/generate-channels.sc). Those files are meant to be consumed by coursier as URL-based channels, in place of the io.get-coursier:apps and io.get-coursier:apps-contrib JARs published on Maven Central. A new update-channels workflow regenerates and commits them upon pushes to main, and the build workflow runs the script on PRs to validate the app descriptors.

With the new Maven Central publishing limits, I'd prefer to switch to a mutable-JSON-on-GitHub model for the apps, rather than a static-JARs-on-Maven-Central one.
This PR prepares that by generating those JSON files automatically on the CI, and opening PRs that maintainers need to merge later on. That's basically the same model as coursier/jvm-index, where coursier consumes its JSON index from GitHub, and where I also disabled automated publishing on Maven Central (for the same reason as here).
