Build for 32-bits broken

Upgrade to 4.4.0 version is blocked for Alpinelinux as x86/armv7/armhf fails (other arches are 64-bits and passing)

See https://gitlab.alpinelinux.org/alpine/aports/-/merge_requests/90885/pipelines

Start with the referenced Alpine pipeline and inspect src/deps/couchbase-cxx-client/core/websocket_codec.cxx at lines 448-451 and 522, where the 32-bit build errors occur. Use the x86, armv7, and armhf pipeline results to verify completion; done means the PHP 8.4 Couchbase package builds successfully for those architectures.
