chore: update DeviceTests to net8

[vaind]

This original exception seems resolved now...

Many tests currently fail with the following exception:

System.InvalidCastException : Specified cast is not valid.

Which looks very similar to https://github.com/dotnet/runtime/issues/93770 and that should be fixed by https://github.com/dotnet/runtime/pull/94469 so I think we need to wait till that makes it to a release.

but there's a new one, which is weird because we have exactly that setting: https://github.com/getsentry/sentry-dotnet/blob/7108689f09addc2f678cb44ea0ead6bb7fa1c1af/Directory.Build.props#L100
