chore(Search, Typescript): Fix for Search methods not allowing passing of shared service method options.

[jbottigliero]

The previous definition here was causing Typescript errors when passing SDK-supported method options (e.g. headers)

Since these methods do not use the satisfies ServiceMethodDynamicSegments (and return their own Generic) the type needs to be explicitly defined.
