Netlify-cms: Documentation states to use value_field and search_fields but latest version of NetlifyCMS reports missing valueFields and searchFields

[kylekirkby]

Describe the bug
Documentation is not consistent with schema errors being reported by NetlifyCMS.

To Reproduce

1. See the documentation here for the relation widget here: https://www.netlifycms.org/docs/widgets/relation/
2. Use value_field or search_fields in a relation widget and see the schema error reported.

Error loading the CMS configuration
Config Errors:
config should have required property 'valueField'
config should have required property 'searchFields'
Check your config.yml file.

Expected behavior
Documentation to be consistent with schema errors that are being reported. Which of the above should I use?

Applicable Versions:

• Netlify CMS version: 2.10.56
• OS: Ubuntu 20.04
• Browser version: Chromium
