[Bazel] Bump libzmq dep to 4.3.5.bcr.3

[shameekganguly]

🦟 Bug fix

Summary

This fixes clang build under --copt=-Werror --per_file_copt=+external/.*@-Wno-everything. Verified with

$ bazel build --copt=-Werror --per_file_copt=+external/.*@-Wno-everything --action_env=CC=/usr/bin/clang :all

The --per_file_copt setting excludes warnings from external dependencies from causing build failure. However, libzmq in particular uses rules_foreign_cc:cmake to build, which does not respect the --per_file_copt setting. There was one error from -Wmissing-braces in libzmq that was fixed in BCR .

This PR updates the libzmq dep version to fix the build.

Also requires in a version bump for bazel-contrib/.github/.github/workflows/bazel.yaml which we use for bazel CI since there is an error with rules_java brought in transitively with the libzmq update. Now, Bazel 8.x CI uses bazel 8.0.0 instead of 8.0.0rc1.
