Missing i18n support in ToolCall component

[keqingrong]

Description

Hello! 👋

In the file ToolCall.tsx at line 76, the UI text is hardcoded in English:

docsearch/packages/docsearch-react/src/ToolCall.tsx

Line 76 in 104f7d1

found {numberOfHits || 0} results

It would be great if this text could be translated via configuration.

Thank you!
