Subject: [PATCH] fix(@schematics/angular): skip SSR routing prompt in
 webcontainer

Apparently `inquirer` requires `async_hooks` which isn't supported in webcontainers, therefore prompting the user fails. Instead we always fall back to the default option.

See: https://github.com/SBoudrias/Inquirer.js/issues/1426
(cherry picked from commit 173dc0eeac0543e600244d40a2b94505904cbe66)
