Unknown variant 'find_in_page' in WebSearch

[edwin0cheng]

When I tried to use web search tool, the following errors occured.

Error: failed to deserialize api response: error:unknown variant `find_in_page`, expected one of `search`, `open_page`, `find` at line 155 column 4 content:

According to open-ai doc, it seem like they change the name of find to find_in_page.

On the other hand, the url and other fields inside these structure should be mark as optional as doc mentioned in our side too.
