Close #64

Key Changes:

1. Added Aspire Project:

   • Introduced an Aspire project with two profiles:
     • https: For running SampleWebApplication with full functionality.
     • tests: For running OGC API conformance tests.
   • Replaced the previous Docker Compose setup for OGC tests with the Aspire-based configuration.

2. Updated SampleWebApplication:

   • Enhanced the application to align with the new Aspire-based architecture.

3. Fixed Bug in Schemas:

   • Resolved an issue where SchemaGenerator was receiving only one IFeatureProvider when multiple providers were present. This caused schemas for some collections to be unavailable.
   • The bug could only occur in projects using more than one IFeatureProvider.

4. Updated Tests:

   • Fixed Schemas tests to account for the resolved bug.
   • Corrected namespaces in the test suite for consistency.

5. Documentation Updates:

   • Updated documentation to reflect the new Aspire-based setup, including instructions for running the application and OGC tests.
