jesse fd318b1b79 fix(hooks): replace BASH_SOURCE with POSIX-safe $0 ...

Replace ${BASH_SOURCE[0]:-$0} with $0 in hooks/session-start and the
polyglot-hooks docs example. BASH_SOURCE uses bash array syntax that
causes 'Bad substitution' on systems where /bin/sh is dash (Ubuntu).

Since session-start is always executed (never sourced), $0 and
BASH_SOURCE give the same result. Tested on Linux (bash + dash) and
Windows (Git Bash via CMD and direct).

Based on #553, closes #553.
