https://github.com/isaacbrodsky/duckdb-zipfs/actions/runs/15729615119/job/44327438225?pr=39

Fails with:

CMake Warning at CMakeLists.txt:1357 (message):
  Extension 'zipfs' has a vcpkg.json, but build was not run with VCPKG.  If
  build fails, check out VCPKG build instructions in
  'duckdb/extension/README.md' or try manually installing the dependencies in
  /home/runner/work/duckdb-zipfs/duckdb-zipfsvcpkg.json

There doesn't seem to be an option on the code quality check job to enable vcpkg.
