refactor(localize): ensure schematic code runs as commonjs (#44016)

The schematic code in `@angular/localize` is currently still emitted
as CommonJS, while the rest of `@angular/localize` is strict ESM (which
is also denoted through `type: module` in the package.json file).

The schematic code is currently imported as CJS from the CLI so it
is not a problem right now. Still, it is safer to ensure the code
for schematics is properly picked up as CJS through a local
`package.json` file resetting `type: module` to `type: commonjs`.
