build(deps): bump httpx2 from 2.7.0 to 2.10.0 in /clients/py

[dependabot]

Bumps httpx2 from 2.7.0 to 2.10.0.

Release notes

Sourced from httpx2's releases.

v2.10.0

Highlights

🚀 Performance and memory improvements

• Sending large HTTP/2 request bodies no longer copies the body quadratically - sending a 256 MiB body went from ~36s to under 0.1s (pydantic/httpx2#1127).
• SSE parsing is up to 35x faster on highly fragmented streams (pydantic/httpx2#1117).
• Cookie extraction is now skipped for responses without a Set-Cookie header, making typical requests roughly 8% faster (pydantic/httpx2#1107).

🕸️ WebAssembly / Emscripten support

httpx2 now runs on Pyodide / Emscripten, using a JavaScript fetch-based transport defined in httpx2-jsfetch (pydantic/httpx2#1119, pydantic/httpx2#1114). Thanks @​hoodmane!
