Continuous integration (CI) tools for Julia package registries, including registry consistency testing, automatic merging (automerge) of pull requests, and automatic TagBot triggers
Registry consistency tests: we need to add a test that in `Versions.toml`, the only allowed keys (for each version) are `git-tree-sha1` and `yanked` #454
See https://github.com/JuliaRegistries/General/pull/65552#discussion_r936820459 and https://github.com/JuliaRegistries/General/pull/65562 for an example where this test would have been useful.
