chore(ci): download hyperd from Java API bundle in npm-build-publish (#121)

The npm-build-publish workflow still used the C++ API bundle URL
(tableauhyperapi-cxx-*) and its SHA-256 hashes for downloading hyperd.
PR #121 switched hyperdb-bootstrap to the Java bundle (because the C++
macos-arm64 zip ships an x86_64 hyperd — upstream packaging defect), but
missed this workflow which downloads hyperd independently for the npm
package build.

Switch the URL template from cxx → java and update the per-platform
SHA-256 hashes to the Java bundle values (same ones verified and pinned
in hyperdb-bootstrap/hyperd-version.toml).
