Add .http files for all API examples

[Copilot]

Added standardized .http request files for all 20 API example projects to enable quick testing and exploration of versioning functionality.

Description

Each .http file contains basic GET requests demonstrating API versioning across different versions. The files focus on showcasing how to call versioned endpoints using both query string and URL segment versioning patterns.

Coverage

• ASP.NET Core: 6 WebApi + 5 OData examples
• ASP.NET (Legacy): 4 WebApi + 5 OData examples

Structure

Each .http file includes:

• Configurable @baseUrl variable
• Basic GET requests with different API versions (0.9, 1.0, 2.0, 3.0)
• Query string versioning (?api-version=X.X)
• URL segment versioning (/api/vX.X/)
• OData query examples ($select, $filter, $expand) for OData endpoints
• Deprecated version examples (v0.9) where applicable

Example

###
# MinimalOpenApiExample - ASP.NET Core Minimal API with OpenAPI and Versioning
###

@baseUrl = http://localhost:5000

### Orders - Get by ID - Version 1.0
GET {{baseUrl}}/api/orders/1?api-version=1.0

### Orders - Get All - Version 2.0
GET {{baseUrl}}/api/orders?api-version=2.0

### People - Get All - Version 3.0
GET {{baseUrl}}/api/v3.0/people

Files are compatible with Visual Studio, VS Code REST Client extension, JetBrains HTTP Client, and other HTTP file editors.
