docs: Fix a few typos

[timgates42]

There are small typos in:

• docs/configuration.rst
• docs/integrations.rst
• docs/overview.rst
• ziggurat_foundations/models/init.py
• ziggurat_foundations/models/services/resource.py
• ziggurat_foundations/models/services/user.py

Fixes:

• Should read resource rather than resouce.
• Should read official rather than offical.
• Should read implementation rather than implementaion.
• Should read function rather than fuction.
• Should read following rather than follwing.
• Should read explicit rather than explict.
• Should read easily rather than easly.
• Should read dynamically rather than dynamicly.
• Should read assigning rather than assiginging.
