module: mark require(esm) as stable

This has been released to all active LTS release lines and many
popular packages have been shipping ESM-only distributions based
on the existence of this feature on active LTS. The current documented
behaviors are unlikely to change in a breaking manner within a major
release - as everything with the module loaders, there can always be
subtle changes to undocumented surface that can break edge cases that
assume undocumented behaviors, due to Hyrum's law; but the stability
of this feature is now not different than any other stable parts of
the module loader. It's time to mark it as stable.
