Restore operations are constantly failing in CI

[jamescrosswell]

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.

Objective Sharpie errors might be alleviated by switching to the new .NET tool available via NuGet:
