Description

For before parameter in npm config, value is of type string, for example before = 2023-02-09T08:45:22.778Z.
packument function of pacote package, expects before as js Date type.
It seems to me that it is necessary to add a date type conversion in the normalizeOptions function in packages/angular/cli/src/utilities/package-metadata.ts

Minimal Reproduction

1. Add before parameter to npm config (.npmrc file) - before = 2023-02-09T08:45:22.778Z
2. Run script ng add @angular/material

Exception or Error

`Unable to load package information from registry: this.before.toISOString is not a function`
