Update URL to find `app_id`
Update URL to find `app_id`

`https://app.intercom.io/a/apps/_/settings/api-keys` returns "We couldn't find the page you're looking for". This change updates the URL to `settings/web` which has the `app_id` in the script example (I'm not sure if there's a better place to link to?).
