Added *.slnx with Xml conditions to OperationConfigDefault.

[karl-sjogren]

Problem

*.slnx files doesn't support conditional processing as described in #8784

Solution

Added *.slnx with ConditionalType.Xml in OperationConfigDefault.cs.

Checks:

• Added unit tests

I've added tests, but I'm running into some problems.

1. Can't build the main branch using build.sh, I'm getting a ton of IDE0055 errors all over the project.
2. If I disable IDE0055 in editorconfig the project builds, but I get 8 failed tests in Microsoft.TemplateEngine.Edge.UnitTests, still in main.
3. Due to the failed tests I'm not even sure if it gets to running the test I added in End2EndTests.cs.

CI seems to pass though, even for OSX, so not sure why it is such as problem locally for me.

I'm not really sure why it would be failing for you locally...best guess is some random configuration thing or out-of-date files not getting updated properly. I tend to trust CI to have a nice, clean environment prior to running tests.

Update: From this and the comments above, this leads me to believe the test was possibly not run correctly

I tried to build this on Windows now as well and got another error (this happens both in my fork and if I try the this repository so it doesn't seem to be related to my changes).

  Microsoft.TemplateEngine.Mocks net10.0 failed with 1 error(s) (1,7s)
    X:\github\templating\test\Microsoft.TemplateEngine.Mocks\MockInstallerFactory.cs(11,22): error IDE0044: Make field readonly (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/style-rules/ide0044)

Maybe this is is something that changed since I got the latest .NET10 preview? It didn't have this warning for other any of the other target frameworks.

Did a quick (local) fix for that though and it builds and my tests passes on Windows so it seems to be something weird with building on my Mac. I can create a seperate issue for that if needed but it passes CI on OSX so I would say that my PR is probably fine.

LGTM, thanks!
