…schema (#9867) ## Background A small percentage of the time when using the Gemini "URL Context" feature we get a Zod validation error on the response due to a missing title property. ## Summary Added `.nullish()` to `groundingChunks[].web.title` and `groundingChunks[].retrievedContext.title`. Notes: * I've personally observed the missing `title` property only on `groundingChunks[].web.title`. I'm guessing that the same situation could occur on `groundingChunks[].retrievedContext.title` and they should have the same schema. * I used `.nullish()` instead of `.optional()` to maintain consistency with the rest of `packages/google/src/google-generative-ai-language-model.ts`, though I have only observed a missing (`undefined`) `title` property, not a `title: null`. ## Related Issues Fixes #9842
