12423: Disable faulty subject-case commitlint rule r=korthout a=korthout

## Description

<!-- Please explain the changes you made here. -->

We had disabled the subject case 'always' 'lowercase' rule, because our CONTRIBUTING guide does not specify any rules for casing.

However, from `@commitlint/config-conventional` we inherit a different rule:

Never
- sentence-case
- start-case
- pascal-case
- upper-case

This meant that we still get an error on a commit message like:
```
fix: Do the thing
subject must not be sentence-case, start-case, pascal-case, upper-case [subject-case]
```

I've swapped the subject-case rule so we disable the inheritted rule.
