Subject: [PATCH] [release/7.0.2xx-xcode14.3] [devops] Ignore any errors when
 printing the system's .NET version on Windows. (#18126)

Because Windows sometimes gives this random and somewhat cute error:

    Unhandled exception: System.IO.FileNotFoundException: Retrieving the COM class factory for component with CLSID {177F0C4A-1CD3-4DE7-A32C-71DBBB9FA36D} failed due to the following error: 8007007e The specified module could not be found. (0x8007007E).

    ##[error]PowerShell exited with code '1'.

Despite the scary-looking log, nothing bad actually happens, so just complete
ignore any errors whatsoever.
