求改JS脚本，将网页中的英文替换为中文，支持包含加粗的文本

大家好，我在使用油猴脚本制作一个网页游戏“卡片战斗先导者OD”的汉化
Dulst Card game platform https://dulst.com/overdulst/cards/31853506/Vairina-Valiente
如上↑，我要汉化这个网站的UI、卡名、效果等信息，现在在大段的效果文本上遇到了一个问题，举个例子↓

请看，这是一整句效果，但是却被加粗的给隔开了，如果凑合分两段汉化，非常影响阅读和效率，并且未来会遇到更多此问题。
【下面是我抄来的代码，求帮忙改改，使其能将被加粗分开的当做一整句话，谢谢！Q3Q
（中间的翻译太长了，所以节选了一段）
