Update all script shebangs to use /usr/bin/env interpreter instead of /bin/interpreter

This is required to support systems where bash doesn't reside in /bin (such as NixOS, or the *BSD family) and allow users to specify a different interpreter version through $PATH manipulation.

```release-note
Use /usr/bin/env in all script shebangs to increase portability.
```
