Make Turso preload sanity check non-fatal

Turso v0.5.3 does not implement sqlite3_set_authorizer, which pdo_sqlite
calls during PDO construction, so opening a SQLite PDO connection panics
the Turso library. Mark the diagnostic step as continue-on-error so the
rest of the job still runs and produces a PHPUnit report.
