If scripts need `bash`, don't say to use `sh`

[swolchok]

🐛 Describe the bug

On Debian systems, sh isn't bash, it's dash. I haven't tested every script, but https://github.com/pytorch/torchchat/blob/main/docs/quantization.md says to run sh torchchat/utils/scripts/build_torchao_ops.sh, but this script fails unless run with bash on my Raspberry Pi 5.

Would be useful to run linx + aarch64 as part of regression testing to catch similar items. #1350 adds running on the linux/aarch64 combo. I think I have the right config name, but we need to enable the corresponding runner for torchchat to make this happen. (And confirm the runner name used in the test matches whatever the runner is known as.)

@mikekgfb just fixed in #1437

Thanks for the flag
