Updates the remaining .NET 11 GA references for analyzer defaults, code-analysis rules, and obsoletion diagnostics.

  • Analyzer configuration: Clarify target-framework-based AnalysisLevel defaults and refresh the .NET 11 analyzer overview. Pin to .NET 10 rules with: 
    <PropertyGroup>
  <AnalysisLevel>10</AnalysisLevel>
</PropertyGroup>
  • Code-analysis rules: Refresh .NET 11 default-status tables; add CA1517, CA1876, CA2027, and CA2028 to the rule articles, indexes, and navigation. Mark CA1878 as not enabled by default in .NET 11.
  • Obsoletion coverage: Add SYSLIB0063 to the .NET 11 obsoletion summary. Review the remaining source-generator, EXTOBS, and EditorConfig items; existing documentation covers them, and the reported Roslyn IDs are internal diagnostics.
