FIX: CI Sample Test project failure & MacOS failures

[ritamerkl]

Description

The test-samples.yml hasn't been touched since 2022 and the macos-12 image has since lost its .NET installation (or the package-validation-suite started requiring it). The macos-13 image is what the mobile CI jobs use and is actively maintained.

This fixes the Sample Test project CI failure.
