Optional flag to add/replace registry in publishConfig

[TimberBro]

I'm using clean publish to upload project dependencies to corporate npm registry, that doesn't support mirroring.
Some packages contains fields to prevent publishing or allow publish to specific registries: https://docs.npmjs.com/cli/v10/using-npm/registry#how-can-i-prevent-my-package-from-being-published-in-the-official-registry
In that case I'm not able to publish it, until I manually change or delete these fields.

My suggestion is to add flag, if it's provided, script deletes private field to be able to publish the package and set the value of "publishConfig":{"registry":""} to value from flag.

What do you think about that?

Can you use before-script option with custom script?

Since it is a rare feature I think before-script will feat it better.
