deps: bump npm-registry-fetch from 14.0.5 to 15.0.0

BREAKING CHANGE: the underlying fetch module now uses `@npmcli/agent`. Backwards compatibility should be fully implemented but due to the scope of this change it was made a breaking change out of an abundance of caution.

Bumps [npm-registry-fetch](https://github.com/npm/npm-registry-fetch) from 14.0.5 to 15.0.0.
