feat(IT Wallet): [SIW-1901] Deferred issuance for credential (#6549)

## Short description
This PR introduces the handling of remote configuration for the
`ItwIssuanceCredentialFailureScreen`. If a
`deferred_issuance_screen_content` is present in `itw` config, the title
and description from the remote config are used. Otherwise, fallback
values are used.

## List of changes proposed in this pull request
- add a new selector `itwDeferredIssuanceScreenContentSelector` in
remote config

## How to test
Using a proxy, add the following object to the `itw` remote config.
Also, check the normal scenario without this object to ensure fallback
values are used correctly.

```
      "deferred_issuance_screen_content": {
        "title": {
          "it-IT": "La Motorizzazione Civile ha preso in carico la tua richiesta",
          "en-EN": "La Motorizzazione Civile ha preso in carico la tua richiesta"
        },
        "description": {
          "it-IT": "Riceverai un messaggio in app per continuare appena La Motorizzazione Civile l'avrà elaborata.\n\nIn periodi di alta richiesta il processo potrebbe richiede alcune ore o alcuni giorni.",
          "en-EN": "Riceverai un messaggio in app per continuare appena La Motorizzazione Civile l'avrà elaborata.\n\nIn periodi di alta richiesta il processo potrebbe richiede alcune ore o alcuni giorni."
        }
      }
```
