Issue for JuliaRegistrator

@JuliaRegistrator register()

This issue only contains the command `@JuliaRegistrator register()` and does not name any file, test, or code entry point. Start by reading the issue thread and checking how this repo wires JuliaRegistrator (usually via GitHub metadata/workflow configuration) to confirm whether release registration is still intended. No code changes are specified, so first verify if the registration request is already handled or obsolete in later comments. Done means the registrator action is clearly accepted/processed or the request is deferred as outdated.
