docs: Fix a few typos (#651)

There are small typos in:
- docs/modeltranslation/admin.rst
- docs/modeltranslation/installation.rst
- docs/modeltranslation/related_projects.rst
- modeltranslation/admin.py
- modeltranslation/management/commands/sync_translation_fields.py
- modeltranslation/tests/models.py

Fixes:
- Should read `similar` rather than `similiar`.
- Should read `whose` rather than `whos`.
- Should read `original` rather than `orginal`.
- Should read `missing` rather than `missings`.
- Should read `consistent` rather than `consistant`.
- Should read `compatibility` rather than `compatibiliy`.
