還沒有人認領這個 Issue。

### How are you using the lua-language-server?

Nvim

### Which OS are you using?

MacOS

### What is the issue affecting?

Hover

### Expected Behaviour

code should be able to use `@see` annotations that don't necessarily map to a known symbol.

### Actual Behaviour

unknown symbols are rendered as "strikethrough": https://github.com/LuaLS/lua-language-server/blob/8c32d8f95f28f8bc064533031898abfb7dea58b0/script/core/hover/description.lua#L144

### Reproduction steps

1. add a `@see bogus` annotation
2. hover the annotation in any LSP client

從 script/core/hover/description.lua 第 144 行附近開始，然後使用錯誤的 @see 註解重現此問題，並在 LSP 用戶端中將游標停留在其上。確認對無法解析的 @see 符號的處理，並驗證完成後的行為不再將未知符號呈現為帶刪除線的形式。
