JavaScript production guide needs to be updated for Angular 12

[mraible]

Affected page(s):

https://developer.okta.com/docs/guides/deploy-your-app/javascript/

Describe the problem(s):

Angular 12's ng build does a production build by default, so --prod is no longer needed.

https://angular.io/cli/build

See https://github.com/okta-samples/okta-angular-sample/blob/main/package.json#L5 to see what the latest version of the Angular CLI generates for scripts.

If possible, describe a proposed fix:

Update scripts to match what the Angular CLI generates.
