• Removed a print introduced in Refactor CubeCL slices #3104
• Adjusted conv2d_should_match_reference_backend_bias_regression tolerance for something more reasonable
• Disabled crates cache on linux-std (stable) runner
  • With all the ongoing changes we end up with a bloated cache and have to delete it over again. The tests take ~6min more without all the cached crates, but much more convenient to avoid CI failure so I think the benefits outweigh the cost.
