Nuxi add command not working with private repositories where auth is required

[gapipro]

Normal usage of nuxi is via: npx nuxi@latest module add ui

add command reads custom registry setting from .npmrc file but it reads just the URL. Not the _auth settings that should also be taken into consideration when creating a fetch request by appending correct headers.

.npmrc example:

registry=https://<repo-path>/
//<repo-path>:_authToken="<token>"

There are also other properties that can be set in .npmrc file. Example of implementation: pnpm/pnpm#8207
