chore(ci): pin surrealdb test server to the v2 image for the 1.3 client

[gustavovalverde]

The SurrealDB adapter's test bootstrap picked its Docker image tag by scraping the first page of Docker Hub's tag list for the newest v2.x release. That list has since filled up with rolling-*, nightly, and v3.x tags, so every v2.x tag has aged off page one and the scrape now returns nothing. With an empty tag, the script runs docker run surrealdb/surrealdb: start ..., which Docker rejects with invalid reference format. No server ever starts, so the test's db.connect("ws://0.0.0.0:8000") fails with ECONNREFUSED, and the client's version probe against the unreachable host produces a misleading "Unexpected token '<'" log that just reflects the missing server, not a separate bug.

This replaces the registry scrape with the floating surrealdb/surrealdb:v2 tag, which resolves to a current v2 release compatible with the pinned 1.3.x JS client. It also swaps the blind 5-second sleep for a poll against the server's /health endpoint and uses a trap ... EXIT to guarantee the container stops while preserving the test suite's exit code under set -euo pipefail. No runtime source, dependency, or published package changes; this only fixes the test bootstrap script.
