Enforce code style defined in `.editorconfig`

make https://github.com/dotnet/orleans/blob/main/.editorconfig#L509C1-L509C48

# IDE1006: Required naming style
-dotnet_diagnostic.IDE1006.severity = suggestion
+dotnet_diagnostic.IDE1006.severity = warning

right now the code styles are not enforced.

the only issue I see with enforcing is that there isn't a fix-all option

I believe copilot would be able to do most of the work since there should be almost no cross-file dependencies (no need to understand complex references between files)

Someone hacked together a way to do it: https://github.com/mwagnerEE/Wagner.NamingStyles
