🔁 feat: Allow "http" as Alias for "streamable-http" in MCP Options (#8624)

Browse source 
- Updated StreamableHTTPOptionsSchema to accept "http" alongside "streamable-http".
- Enhanced isStreamableHTTPOptions function to handle both types and validate URLs accordingly.
- Added tests to ensure correct processing of "http" type options and rejection of websocket URLs.
