module: runtime deprecate module.register()

[GeoffreyBooth]

Building on #62395, this runtime-deprecates module.register().

I’m not sure when we want to land and release this; I think the options are basically either:

1. When module.registerHooks() goes stable, hopefully sometime before 26 goes LTS; module: doc-deprecate module.register() #62395 (comment)
2. In 26.0.0; the doc-deprecation is backported to the 25.x line, and the runtime deprecation is 26+; module: doc-deprecate module.register() #62395 (comment)

I’m opening this now in case the team wants to do the second option. cc @nodejs/loaders @nodejs/userland-migrations
