ci: define the test dataset inline instead of fetching it from the registry (#83)

`spice add spiceai/quickstart` makes every run depend on the Spicepod registry,
which is currently returning a body the CLI cannot unpack:

  Invalid argument: Failed to extract Spicepod archive: invalid Zip archive:
  Could not find EOCD

Declaring the same dataset inline removes the dependency. Covers both the Unix
step (heredoc) and the Windows step (PowerShell here-string).

Verified locally: taxi_trips loads and is queryable within seconds.

Mirrors spicepy#176.
