test: bump SQL-on-FHIR beforeAll timeout to 180s

The previous commit moved generation from describe-discovery (no
timeout) into `beforeAll`, which inherits bunfig's `timeout = 30000`.
SQL-on-FHIR fetches `https://build.fhir.org/.../package.tgz` on cold
cache from GH runners and routinely exceeds 30s; the hook timed out,
got retried, and OOM-killed the suite.
