I'm learning about the configuration of some rules. And I found subject-case's configuration is inconsistent in different README.md.

Expected Behavior

 According to @commitlint/config-conventional/index.js, the default values of subject-case are ['sentence-case', 'start-case', 'pascal-case', 'upper-case'].

Current Behavior

 In docs/reference-rules.md:

 And In @commitlint/config-conventional/README.md:

 The condition, rule and value are inconsistent.

Possible Solution

 I have a suggestion to modify these two files as follows:
  docs/reference-rules.md

subject-case

• condition: subject is in one of the cases ['sentence-case', 'start-case', 'pascal-case', 'upper-case']
• rule: always
• value:

['sentence-case', 'start-case', 'pascal-case', 'upper-case']

• possible values:

[
  'lower-case', // default
  'upper-case', // UPPERCASE
  'camel-case', // camelCase
  'kebab-case', // kebab-case
  'pascal-case', // PascalCase
  'sentence-case', // Sentence case
  'snake-case', // snake_case
  'start-case' // Start Case
]

 @commitlint/config-conventional/README.md:

subject-case

• condition: subject is in one of the cases ['sentence-case', 'start-case', 'pascal-case', 'upper-case']
• rule: always
• level: error

Your Environment

Can I send PR for this? Thanks for taking note of this question.
