Fix UpdateMockWebServerDispatcher classpath lookup (#975)

The recipe asked for `okhttp-4.10` via `classpathFromResources`, but
that artifact is only bundled in the test type table — production runs
of the recipe (e.g. via the Moderne CLI) fail with
`IllegalArgumentException: Unable to find classpath resource
dependencies beginning with: 'okhttp-4.10'` whenever a project has
`mockwebserver` on its classpath.

The template snippet only references `MockResponse` and `.build()`
(itself a 5.x-only method, so the parser is already lenient about
unresolved members), so dropping the unused `okhttp-4.10` request is
sufficient and matches the sister `UpdateMockWebServerMockResponse`
recipe, which uses just `mockwebserver3`.
