Bump aiobotocore from 3.7.0 to 3.9.0

[dependabot]

Bumps aiobotocore from 3.7.0 to 3.9.0.

Release notes

Sourced from aiobotocore's releases.

3.9.0

• bump botocore dependency specification to support "botocore >= 1.43.3, < 1.43.57" (#1665, #1668, #1675)
• bump aiohttp dependency specification to support "aiohttp >= 3.14.0, < 4.0.0" (#1667)
• run the optional httpx backend on trio in addition to asyncio, via anyio primitives, so aiobotocore is usable from trio-based projects (closes #749) (#1667)
• prefer httpx2 — Pydantic's maintained, API-compatible fork of httpx — for the optional httpx backend, adding a new aiobotocore[httpx2] extra; the existing aiobotocore[httpx] extra keeps working but now installs the deprecated legacy httpx package and emits a DeprecationWarning when used (#1669)
• fix the release-drafting workflow silently reporting success when the agent never ran (#1664)

3.8.0

• bump botocore dependency specification to support "botocore >= 1.43.3, < 1.43.47" (#1605, #1606, #1635, #1651, #1655)
• port botocore 1.43.24's long-polling no-retry signal (handler_response is False) through the async retry path so retries don't block the event loop with a synchronous sleep during backoff (#1606)
• fix AIOHTTPSession/HttpxSession blocking the event loop on the first request per proxy: SSL context creation (certificate loading via load_verify_locations/load_cert_chain) now runs in a thread via asyncio.to_thread instead of directly on the loop (closes #1469) (#1587)
• restructure StreamingBody to subclass botocore.response.StreamingBody (dropping the wrapt.ObjectProxy wrapper) and add full httpx API parity — read(amt), readinto(), readlines(), async iteration, iter_lines()/iter_chunks(), tell(), close() — where read(amt) previously raised ValueError; note that AioStreamingBody.__aenter__ now returns self instead of the raw aiohttp ClientResponse (use .raw_stream for the underlying response) (closes #1365) (#1539)
