fix: Python 3 compatibility and misc improvements

Python 3 fixes:
- bin/git-open: Use python3 shebang, decode bytes, add error handling
- bin/tweet: Use python3 shebang, fix print() syntax, proper exit code
- .aliases: Change python to python3 in Django and Docker aliases
- .functions: Change dj() to use python3

Bug fixes:
- .functions: Replace undefined print_error with echo
- .functions: Add pygmentize availability check in json()
- .profile: Add existence checks for OS-specific files, use $HOME
- .zshrc: Fix duplicate powerlevel10k loading, add file check
- bin/git-flake8: Add missing shebang
- bin/splash: Fix typo 'coway' to 'cowsay'

Deprecations:
- bin/gitio: Mark as deprecated (git.io shut down in 2022)
- setup/requirements.pip: Remove pinned ansible 2.3.2.0 (EOL), use latest
- setup/requirements.pip: Remove deprecated piprot
