Restore operations are constantly failing in CI

### Description

The iOS device tests are frequently failing in CI, which is super frustrating. For example:
https://github.com/getsentry/sentry-dotnet/actions/runs/23469005245/job/68287438952

The error when running `pwsh ./scripts/device-test.ps1 ios -Build` in the Build iOS Test App task is:
```

Ideally we could come up with a solution that retries (with a backoff)... so simulating `Microsoft.Extensions.Http.Resilience` during dotnet restore operations.
