fix: use #!/usr/bin/env bash as shebang instead of #!/bin/bash

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[2]: Leaving directory '/home/flokli/dev/numtide/manifoldfinance/talos'
make[1]: *** [Makefile:274: fmt-protobuf] Error 2
make[1]: Leaving directory '/home/flokli/dev/numtide/manifoldfinance/talos'
make: *** [Makefile:277: fmt] Error 2
```
