[EF Sync] Sync to EF 11.0.0-preview.2.26115.104

[github-actions]

This PR updates EFCore.PG to use the latest EF Core 11.0.0-preview.2 daily build.

Changes Made

• Updated EFCoreVersion and MicrosoftExtensionsVersion from 11.0.0-preview.1.26104.118 to 11.0.0-preview.2.26115.104 in Directory.Packages.props
• Updated .NET SDK version from 11.0.100-preview.1.26104.118 to 11.0.100-preview.2.26115.104 in global.json

Status

⚠️ Partial sync - This PR contains only the version updates. The following steps could not be completed due to network restrictions in the build environment:

Remaining Work

1. Restore packages and build - The Azure DevOps NuGet feed (https://pkgs.dev.azure.com/dnceng/public/_packaging/dotnet11/nuget/v3/index.json) was inaccessible due to network proxy restrictions (403 errors)

2. Fix build errors - Once packages are restored:

   • Investigate and fix any build errors that arise from API changes between preview.1 and preview.2
   • Review EF Core changes at https://github.com/dotnet/efcore comparing preview.1 to preview.2
   • Align code with EF Core patterns and practices

3. Run and fix tests:

   • Handle Check_all_tests_overridden failures (new or renamed tests from EF Core)
     • Add new test overrides in appropriate locations (following base class order, not at end of file)
     • Add AssertSql() calls following the pattern in other tests
   • Handle NpgsqlComplianceTest.All_test_bases_must_be_implemented failures (new or renamed test base classes)
     • Add missing test suites (do not simply add to IgnoredTestBases)

4. Commit any additional changes to this PR
