.NET 6 is ending support in Nov 2024 and we will want to move to .NET 8 before then.

Several projects that were NET 6 were moved to NET 7 as part of this PR

These are the remaining projects

Many, but not all, of these projects publish to the dev feed but it's not clear where, if anywhere, these published libraries are being used and where, if anyplace, to update the version.

• TestLibrary.csproj **Project was unused and deleted by @chidozieononiwu **

Some of these require publishing a binary to the dev feed and updating their respective install versions in their pipeline yml files. Each and every project on this particular list will get updated when the Azure.Sdk.Tools.CodeownersUtils.csproj so these should be done together
