fix(backend): happy-domで外部HTMLをパースする際に関連リソースが読み込まれる問題を修正

[kakkokari-gtyih]

version 10 didn't quite support disabling all of that

I have tested that MfmService (the other code that uses happy-dom) still works fine: the RSS feed for a user is generated correctly, with HTML rendered from MFM

(cherry picked from commit 26e0412fbb91447c37e8fb06ffb0487346063bb8)

What

• happy-domをv15にアップデート
• happy-domで外部HTMLをパースする際に関連リソースが読み込まれるのを修正（この修正はv10では対応不可だったらしい）

Why

無駄かも

Additional info (optional)

v14で見られたメモリリークはv15になるときのリファクタリングで解消されたかもしれないという報告があるけど真偽は不明

Sharkeyでこの変更からしばらくしたあとにメモリ使用量の瞬間的な増加が見られたらしいのでやっぱあかんかもしれない（原因の切り分けまではまだ行われていないので今なにかをするというよりかはそういうことがあったということを覚えておく程度で良い）
