feat(install): make install script posix compliant (#2228)
- update shebang to support posix-compliant shells (like dash) - replace all usages of echo with printf (to normalise) - command variable to fetch_cmd as it overloads a posix - rename complete function to completed as it overloads the bash builtin for completion Co-authored-by: David Knaack <davidkna@users.noreply.github.com>
