fix: subject-case value set to lower-case but input is not properly formatted (prompt-cli)

### Expected Behavior

Setting `subject-case` value to `lower-case` should properly format all text to lower-case. If it moves onto the next step without properly formatting, an error should properly display.

### Current Behavior

1. When I type my subject message in all uppercase, the cli shows it being lower-cased, but when I go to the next step, the subject still displays as all upper-case
2. There is no error that pops up that my text is not lower-case


### Affected packages

- [X] cli
- [ ] core
- [ ] prompt
- [ ] config-angular

### Possible Solution

_No response_

### Steps to Reproduce

```bash
1. Set subject-case rule in `commitlint.config.js`

module.exports = {
extends: ['@commitlint/config-conventional'],
rules: {
'subject-case': [2, 'always', 'lower-case'],
},
};

2. When committing, I type HELLO WORLD as my subject and move to the next stage (body), no error prompt appears that my text is not lower-case. The commit message is currently generated as `fix: HELLO WORLD` instead of `fix: hello world`
```
