Allow `publishConfig.access` to "public" even the package is not scoped

[fisker]

Description

Similar to #749, I don't want different publishConfig in my packages, putting "access": "public" is not harmful.

Is the feature request related to a problem?

Possible implementation

Skip check when publishConfig.access is "public"

This seems to happen due to my internet connection? Not sure..
