This will fix running these scripts on distros without /bin/bash, but
where bash is in $PATH, such as NixOS.
Currently, `make fmt` otherwise fails to run:
```
make[3]: Leaving directory '/home/flokli/dev/numtide/manifoldfinance/talos'
sh: ./hack/fix-artifacts.sh: /bin/bash: bad interpreter: No such file or directory
make[2]: *** [Makefile:163: local-fmt-protobuf] Error 126

make[1]: Leaving directory '/home/flokli/dev/numtide/manifoldfinance/talos'

At the moment only AMIs for AWS, and upload results should be pushed
back to the docs as separate PR.
