Revert "chore(example): regenerate basic-app queries"

The generator's placeholder style is not deterministic across runs: the
same command emitted $1 once and ? the next time, depending on the
database dialect active in the environment. Restoring the committed
output and reverting my earlier regeneration, which was environment
churn rather than an intended change.

Worth a look on its own: a generator whose output depends on ambient
environment makes check:generated-types environment-sensitive.
