CLI doesn't produce a failure related exit code in case of failure

**Describe the bug**
A clear and concise description of what the bug is.

Any error coming from running the CLI doesn't have an exit code that represents a failure. When I run the CLI directly (not by using the github actions action), I don't get an error from it. One example:

```
Run ./node_modules/.bin/swa deploy --no-use-keychain --config-name dev --env pr124

Welcome to Azure Static Web Apps CLI (1.1.4)

Using configuration "dev" from file:

Consider providing api-language and version using --api-language and --api-version flags,
otherwise default values apiLanguage: node and apiVersion: 16 will apply

**To Reproduce**
Steps to reproduce the behavior:

1. Use the SWA CLI manually in github actions
2. Run a command that will fail
3. The workflow will not fail

**Expected behavior**

I expected the CLI to exit with a code that represents a failure, so the workflow would fail.

Inizia dal punto di ingresso ./node_modules/.bin/swa deploy e riproduci il malfunzionamento con il comando di deploy mostrato, utilizzando la configurazione swa-cli.config.json e staticwebapp.config.json del report. Traccia come l’errore di deployment segnalato viene restituito al processo CLI; il lavoro è completato quando un deployment non riuscito produce un codice di uscita diverso da zero e causa il fallimento del workflow.
