ci: add wasm-solana build artifacts to publish workflow

The publish workflow was only uploading and downloading wasm-utxo build
artifacts, causing wasm-solana (and wasm-bip32) to be published to npm
without their dist/ folders. This resulted in broken npm packages that
only contained package.json and README.md.

This fix adds a separate artifact upload step for wasm-solana in the
finalize job, and a corresponding download step in the publish job,
ensuring the built files are included when multi-semantic-release
publishes to npm.
