Fix duckdb/connector recipe: correct the startup log the reader is told to confirm

Step 4 tells the reader to confirm the dataset loaded by looking for
'INFO runtime: Loaded dataset: tpch_customer'. That log message no longer
exists anywhere in the runtime, so the check can never succeed. The runtime
now prints 'Dataset tpch_customer registered (duckdb:customer), results cache
enabled.' from runtime::init::dataset.

The same block also pasted two lines the runtime no longer emits: the
'spiced: Metrics listening' line (the metrics server is off by default on
v2) and 'runtime::opentelemetry: Spice Runtime OpenTelemetry listening on
127.0.0.1:50052' (that listener was removed).

Step 5's result table also predates the column type row the v2 SQL REPL
prints. The data itself is unchanged and still matches TPC-H sf=1.
