Add support for AI Translate Strings method

[andrii-bodnar]

The Crowdin API now includes the AI Translate Strings endpoint in the AI section, allowing users to submit strings for AI-powered translation.

The Crowdin API client libraries should be updated to support this endpoint so developers can trigger AI string translation directly from SDKs.

Hi! I'd like to contribute support for the AI Translate Strings endpoint to this client library.

What it does: The Crowdin API now exposes an AI Translate Strings endpoint under the AI section, allowing users to submit strings for AI-powered translation. The Python client currently doesn't have a method for this endpoint.

Current behavior: There is no way to trigger AI string translation via the Python SDK — developers have to make raw HTTP requests manually.

Expected behavior: A new method (e.g., ai_translate_strings) should be available on the AI resource, consistent with how other AI-related endpoints (like Fine Tuning) are implemented in this client.

Could you please assign this issue to me?.
Thanks!
