[BUG][code-analyzer] Disabled rules are moved to the end of the config file rules list

まだ誰も着手していません。

### Have you tried to resolve this issue yourself first?

- [x] I confirm I have gone through the above steps and still have an issue to report.

### Bug Description

I disabled some rules and recreated the config file. ( see #2013 )

All the disabled rules were moved to the end of the `pmd` section.

But I want to view ALL the PMD rules alphabetized so I know which ones are in there.

### Output / Logs

```shell

```

### Steps To Reproduce

1. Disabled a rule with `disabled: true`
2. Run `echo 'y' | sf code-analyzer config --include-unmodified-rules --rule-selector all --config-file code-analyzer.yml --output-file code-analyzer.yml`
3. See that the disabled rules are moved.

### Expected Behavior

All rules should be alphabetized by their unique key. This extra sort doesn't help anything and only can confuse people.

`sf code-analyzer config` コマンドから始め、提供されたコマンドと `code-analyzer.yml` を使用して問題を再現します。生成された `pmd` ルールリストを調べ、その後、`disabled: true` を持つルールを含むすべてのルールが一意のキーでアルファベット順に並べられており、再生成後もその状態が維持されることを確認します。
