This is great but it's missing the CHANGELOG and CODEOWNERS updates

Looks great! I skipped the contents of the client directory since it's TypeSpec-generated. I think we should push the TypeSpec you authored for the pricing service somewhere like the mcp-pr repo, along with generation instructions - this isn't available in the REST API spec repo.

What does this PR do?
Get Azure Retail Price MCP tool
Documentation: https://learn.microsoft.com/en-us/rest/api/cost-management/retail-prices/azure-retail-prices
API endpoint: https://prices.azure.com/api/retail/prices
Given the documentation and the endpoint, we wrote a typespec for the API and then generated the client. Since we hand-crafted the spec and generated the library ourselves, the best option discussed was to vendor this small client directly into the MCP tools project. The generated client is present in the
\tools\Azure.Mcp.Tools.Pricing\src\Clientfolder.get_azure_retail_pricing MCP tool result
The following prompts are supported with this tool-
Copilot should then clarify how the service works and then ask the user for which SKU under that Azure service they want the price for
