Add NetEvolve.HealthChecks.GCP.BigQuery

[Copilot]

What does this PR do?

Implements health check for Google Cloud Platform BigQuery service using the Google.Cloud.BigQuery.V2 package.

Implementation:

• Health check uses ListDatasetsAsync().ReadPageAsync(1) - lightweight API call to verify service connectivity
• Supports configurable timeout and keyed service injection patterns
• Follows established patterns from GCP.Firestore and GCP.PubSub implementations

Project Structure:

• src/NetEvolve.HealthChecks.GCP.BigQuery/ - Core implementation with options, configuration, and DI extensions
• tests/NetEvolve.HealthChecks.Tests.Unit/GCP.BigQuery/ - 25 unit tests (options, configuration, DI registration)
• tests/NetEvolve.HealthChecks.Tests.Integration/GCP.BigQuery/ - Integration tests with Testcontainers.BigQuery

Usage:

// Configuration-based
services.AddHealthChecks()
    .AddBigQuery("my-check");

// Builder-based with options
services.AddHealthChecks()
    .AddBigQuery("my-check", options => 
    {
        options.Timeout = 5000;
        options.KeyedService = "bigquery-instance";
    });

Why is it important?

Enables monitoring of BigQuery service availability in applications using the established NetEvolve.HealthChecks framework. Completes GCP service coverage alongside existing Firestore and PubSub health checks.
