Update .editorconfig with new style and diagnostic rules

Added `csharp_style_prefer_simple_property_accessors` to promote
simple property accessors with suggestion severity. Disabled
CA1873 warnings for potentially expensive logging. Retained
IDE0305 rule for simplifying collection initialization for
clarity. These changes enhance code style consistency and
suppress irrelevant diagnostics.
