* .NET: Add Web Search sample #3674
* .NET: Fix WebSearch sample to use Responses API built-in web search
Remove incorrect Bing Grounding connection ID requirement from the
WebSearch sample. The web search tool uses the OpenAI Responses API
built-in capability and does not need a connection ID.
- Remove AZURE_FOUNDRY_BING_CONNECTION_ID env var requirement
- Use HostedWebSearchTool() without connectionId properties
- Refactor creation options into local functions (MEAI + NativeSDK)
- Switch from AzureCliCredential to DefaultAzureCredential
- Update README to reflect correct prerequisites
