fix yarn npm publish for scoped packages

this will make yarn berry `yarn npm publish` behave like `npm publish`:
`npm publish` on an already public scoped package will publish it gladly
however for `yarn npm publish`, even if the scoped package is already published publicly
we need to specify the `--access public` argument, or it will fail with 402 (Payment Required)
here I add a check (currently only for yarn berry) for whether the published version of the package is public,
and if so, set publishScoped to true (and don't ask for it)
