web_search support in genkitx-anthropic

[michaelrokosh]

Add native support in the @genkit-ai/anthropic plugin for Anthropic’s web_search tool. This could be implemented via a tools field in the initial config, which gets passed through to the underlying Claude API request.

Let me know if there's currently any workaround to enable this feature.
