On some systems, /bin/sh is a bash symlink and running it will launch
bash in sh compatibility mode. However, bash-specific syntax will still
work in this mode (for example using == or pipefail).
However, on systems where /bin/sh is a symlink to another shell (think:
Debian-based) they might not have those bashisms.
Set the shell in the Makefile, so that it uses bash (since it is already
depending on bash, even though it is calling it as /bin/sh by default),
and add a shebang to pre-commit.sh for the same reason.

Modifying workflows to install python for make commands
Squashing CI tasks to remove repeated steps
Modifying pre-commit.sh to not fail if there are no python file changes
This means that
- we don't have to be always updating the underlying .git/hooks/pre-commit file
- updates to the logic will just work automatically
- the logic of the black logic has been fixed so that AWX_IGNORE_BLACK=1 should work right now
