[Proposal] Allow multiple response overrides

**Is your feature request related to a problem? Please describe.**

Current the SWA configuration file only allow one response override for every HTTP status, which is very limiting.
For example if you're building an app with different localizations bundles, like `/` for the `en` version and `fr/*`, `es/*` etc for the localized version, you cannot configure localized 404 (and others) overrides, only one can exist for the whole SWA.
Angular works likes this using the built-in i18n system: https://angular.io/guide/i18n#deploy-locales, and other frameworks with static builds too.

Netlify doesn't have this limitation, and allows to defined which routes needs to be redirected: https://docs.netlify.com/routing/redirects/redirect-options/#http-status-codes

**Describe the solution you'd like**
In the same idea as proposed in https://github.com/Azure/static-web-apps/issues/527, allowing to set and array for each of the HTTP codes overrides along with an `include` or `source` property to target only specific route paths would work.
