Adds EFCore.ComplexIndexes to the extensions list. I maintain it.

It generates migration SQL for indexes on the nested columns of complex properties, which EF Core 10 models but does not index. The core package is provider-agnostic; separate PostgreSQL and SQL Server packages add provider-specific options (PostgreSQL index methods, expression indexes, exclusion and temporal constraints; SQL Server clustered, covering and online indexes).

EF Core 11 indexes complex-type members natively (dotnet/efcore#31246), so the entry states EF Core 10, the line the packages target.

The entry follows the format of the existing ones: description ending in the supported EF Core versions, then repository and NuGet links, added at the end of the Extensions section.

Adds EFCore.ComplexIndexes to the EF Core extensions catalog, documenting EF Core 10 support for migration-generated indexes on complex-type properties and provider-specific options.

Changes:

• Adds the extension to the Extensions section.
• Documents core, PostgreSQL, and SQL Server indexing capabilities.
• Links to the project repository and NuGet package.
• Review note (nit, 1 vote): Provider-specific features should be distinguished from the core package, with links to the separate PostgreSQL and SQL Server packages.
