fix: fix Invalid regular expression on iOS <= 16.3

[Ljzd-PRO]

What

Use replaceAll instead of RegExp lookbehind assertion.

Why

RegExp Lookbehind Assertions are not supported on iOS 16.3 and below, the web app failed to load (ERROR CODE: APP_IMPORT), and throws an exception:

SyntaxError: Invalid regular expression: invalid group specifier name

@misskey-dev/dev iOS <= 16.3ってサポート対象だっけ

[Sayamame-beans]

前回見た時は16.3以上が動く感じだったようですが…今はどうでしょうか https://github.com/misskey-dev/misskey/issues/12875#issuecomment-1874909977

私はiOS 16.x latestが対象と認識してるので対応しなくていいと認識してた

(browserlistとかを明示的に書いてちゃんとメンテしたほうがいいかも)

これやるとメンテナンス性終わって悲しくなるので16.3以下は切って良さそう

iOS <= 16.3 はサポート範囲外だったのでcloseします 🙏🏻
