docs: Fix a few typos

There are small typos in:
- ajenti-core/aj/config.py
- docs/source/man/config.rst
- docs/source/man/install.rst
- plugins/cron/views.py
- plugins/docker/main.py
- plugins/session_list/README.md

Fixes:
- Should read `certificate` rather than `certificat`.
- Should read `successful` rather than `successfull`.
- Should read `software` rather than `sofware`.
- Should read `mentioned` rather than `mentionned`.
- Should read `currently` rather than `currenly`.
- Should read `connected` rather than `connectd`.
