fix(action): use github.action_path for requirements and .env paths

- cache-dependency-path now points to action's own requirements.txt
  instead of searching the caller's repo (fixes external repo usage)
- .env.example copy now uses action_path prefix

Closes non-forked repo setup-python cache error
