Fix incorrect AddServiceDefaults() method call in Aspire integration docs

[Copilot]

The documentation incorrectly showed builder.Services.AddServiceDefaults() when configuring service defaults in a .NET MAUI app with Aspire integration.

Change

• Fixed method call from builder.Services.AddServiceDefaults() to builder.AddServiceDefaults() in docs/data-cloud/aspire-integration.md (line 191)

Context

AddServiceDefaults() is an extension method on MauiAppBuilder, not on IServiceCollection. The corrected syntax matches the maui-samples implementation.

Before:

// Add service defaults
builder.Services.AddServiceDefaults();

After:

// Add service defaults
builder.AddServiceDefaults();
