fix: Update Shebangs and daily.sh for FreeBSD compatibility (#6413)

* Where shebangs had no flags, updated them to use /usr/bin/env for cross-platform compatibility
Updated daily.sh to support FreeBSD (su has different args, replaced with sudo when not on linux)

* Added myself to AUTHORD.md as per contributor guidelines

* Set all platforms to use sudo rather than su
Re-added missing arguments to sudo
