Feature Request Hover Alias Original and Expanded

まだ誰も着手していません。

Currently there is an option Lua > Hover > Expand Alias that allows defining an alias and instead of seeing the alias-name when using the alias you will see what the alias is made of so `---@alias myType boolean | number` will appear as `boolean | number` instead of `myType`. However, there are circumstances where knowing what the alias is but also what it is made of can be useful. Is there a way we can have a both option here where on hover we can see both the alias name and its expansion? Something like `myType - (boolean | number)`

Lua > Hover > Expand Alias 設定から始めて、型エイリアスのホバー表示を追跡します。エイリアス名とその展開の両方を `myType - (boolean | number)` のように表示するモードを追加し、既存のエイリアス表示モードが変更されていないことを確認します。
