Align capability key to SEP-2133 extensions format (#25)

Browse source 
Both SDKs now use Capabilities.Extensions with key
"io.modelcontextprotocol/interceptors". Previously C# used the short key
"interceptors" and Go used Capabilities.Experimental. SEP capability
example updated to match.

@ -50,7 +50,7 @@ behavior as remote interceptor servers.
During initialization, a lightweight middleware intercepts the `"initialize"`
response and injects interceptor metadata into
`Capabilities.Experimental["io.modelcontextprotocol/interceptors"]`. This
`Capabilities.Extensions["io.modelcontextprotocol/interceptors"]`. This
follows the same pattern as the variants extension
(`io.modelcontextprotocol/server-variants`).
