feat: deprecate certain versions of a module

The module authors sometimes want to deprecate some versions of a module and we want to show that info in registry website.

The suggested design in denoland/dotland#1964 can only deprecate the latest version of a module, but usually the module authors want to deprecate the past versions as well. But because a published version of a module is immutable, the solution in denoland/dotland#1964 doesn't work for the past versions

So we need to have some way to get the input from the module authors and indicate that some versions are deprecated
