Bump projects to .NET 8 and package references to latest available

[carlossanlop]

I was using runfo to download an ios payload and found a TarReader issue dotnet/runtime#103734 . At first I thought the bug was in .NET 7 (the TFM of runfo.csproj) so I cloned the repo, updated it to .NET 8, but the issue was still there.

Anyway, I noticed the project has a bunch of out-of-support TFMs and some packages with vulnerabilities so I decided to update them all.
