docs: Fix a few typos

There are small typos in:
- docs/concurrency-challenges.rst
- examples/ptpython_config/config.py
- ptpython/completer.py
- ptpython/history_browser.py
- ptpython/key_bindings.py
- ptpython/repl.py

Fixes:
- Should read `returns` rather than `retuns`.
- Should read `parentheses` rather than `parethesis`.
- Should read `output` rather than `ouptut`.
- Should read `navigation` rather than `navigaton`.
- Should read `executor` rather than `excecutor`.
- Should read `depending` rather than `deponding`.
