Update Mac and Linux targets to .NET 8 LTS (#1579)

Update the target framework version for Mac and Linux to .NET 8, which
is the latest LTS. .NET 7 is [leaving support on
2024-05-14](https://dotnet.microsoft.com/en-us/platform/support/policy/dotnet-core)
so we need to do this.

Windows is not being updated at this time due our courtesy to Visual
Studio (that bundle the same GCM version across all their versions) who
need Windows 8.x support until.. 2029... 😢
and Windows 10 is required for .NET (Core) 8.

I plan to revisit the .NET Framework to Core on Windows effort after a
discussion with the VS team at Microsoft.
