Minimum TLS 1.2 fails for Azure Web App when TLS 1.3 is enabled
### Steps to Reproduce

1. prowler azure --subscription-ids xx-88ae-4fe8-901a-16e33871e7c7 xx-5c28-4e32-94df-591a5baedf69 --az-cli-auth
2. Azure Web App with TLS 1.3 enabled

### Expected behavior

in file prowler/providers/azure/services/app/app_minimum_tls_version_12/app_minimum_tls_version_12.py

When checking for minimum TLS 1.2, please don't fail on TLS 1.3

### Actual Result with Screenshots or Logs

"Minimum TLS version is not set to 1.2 for app"

```
                if (
                    app.configurations
                    and getattr(app.configurations, "min_tls_version", "") == "1.2"
                ):
                    report.status = "PASS"
                    report.status_extended = f"Minimum TLS version is set to 1.2 for app '{app_name}' in subscription '{subscription_name}'."

```
