Add release notes/changelog/version diff for dependencies in private GitHub repos

[MPV]

These nice features don't work for dependencies whose git repos are private (thus need auth):

• Release Notes
• Changelog
• Version Diff

This is probably because the http client used for those doesn't seem to use the github token:

The linked file doesn't exist anymore. Could any of the maintainers point to the potential places that would need changing to make it work with private repos?

[fthomas]

HttpExistenceClient has been renamed to UrlChecker. I think the Client used by UrlChecker needs do authenticated calls for anything that goes to VCSCfg#apiHost. I once tried this in this old branch (https://github.com/scala-steward-org/scala-steward/compare/topic/VCSClient) but then ran out of steam.

There is now a PR at #2920 that fixes this if someone wants to give it a try.

Great news! Thanks!

Can I try this version with the scala-steward-action?

[fthomas]

Yes, just set the scala-steward-version option of the action to 0.20.0-61-1f0282a6-SNAPSHOT for example. Available snapshot versions are here: https://oss.sonatype.org/content/repositories/snapshots/org/scala-steward/scala-steward-core_2.13/
