Target .NET 7 in Standalone version

[bdovaz]

1. I have added target net7.0 / net7.0-windows in all projects to be able to use an updated code base to .NET 7 with the benefit that you get from it in the standalone / ClickOne version.
2. I have changed the target of the ResXManager project from .NET Framework to .NET 7.
3. I have changed the ClickOnce profile dependencies so that it installs the .NET 7 runtime.
4. I have removed the net472 target in Model / Infrastructure projects because with netstandard2.0 it is already implicit: https://learn.microsoft.com/en-us/dotnet/standard/net-standard?tabs=net-standard-2-0#select-net-standard-version
5. I have replaced WindowsAPICodePack-Shell with Microsoft-WindowsAPICodePack-Shell which is an updated fork, the previous one has compatibility problems being abandoned: https://www.nuget.org/packages/Microsoft-WindowsAPICodePack-Shell/#readme-body-tab

@tom-englert about your #598 (comment) concern.

There have been 4-5 warnings generated when targeting .NET 7 but I think they are all fixable without having to do conditional code. I can solve them or if you want, compile it yourself from this branch and take a look at them to see what to do with each one.

In fact, you can see the wanings here:

Again: Which serious issue would that fix?

[bdovaz]

No serious problem, just not using old frameworks (where possible == standalone version) in a project that is still under development and continuous maintenance.

The benefits are as I say, use a more updated code base and unless any API changes, it is transparent to us. And as you can see, there are 4 or 5 warnings when targeting .NET 7 but they are easy to fix if you want to fix them because I see that the project currently has some other info or warning issues not fixed (I think I remember).

Here you reacted with thumbs up, and now you are doing it just again ❓

I simply had a conflict in a csproj that could be resolved through the GitHub web interface and I fixed it.
