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 (#14521)

* bump happy-dom, disable all JS&c when parsing

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)

* Update Changelog

* lint

* fix possible memory leak
