ci: Build sqld from PR branch in golang-bindings test

The golang-bindings workflow was using ghcr.io/tursodatabase/libsql-server:latest
which is built from main branch. This caused protocol mismatches when testing
Hyper 1.0 migration PRs.

Now the workflow builds sqld from the PR branch and runs it directly,
ensuring client and server versions match.
