NeoVim

### Which OS are you using?

Linux

### What is the issue affecting?

Diagnostics/Syntax Checking

### Expected Behaviour

Enum members can contain `#` character

### Actual Behaviour

The LSP diagnostic reports an error on using it

### Reproduction steps

1. Create an enum alias with members containing `#`
Given the following alias
```lua---@alias component_url
---| "/vfx#impact_fx_creator"
---| "/sfx"
---| "/player#player_upgrader"
---| "/cauli"
---| "/game_over_ui"
---| "/in_game_ui"

```
2. Notice that the type check considers the right-hand of `#` as a comment even though it's in the string
```lua
---@type component_url
local d = "/vfx#impact_fx_creator"
```
4. See error
```
Diagnostics:
1. Cannot assign `string` to parameter `"/cauli"|"/game_over_ui"|"/in_game_ui"|"/player#"|"/sfx"...(+1)`.
- `string` cannot match `"/cauli"|"/game_over_ui"|"/in_game_ui"|"/player#"|"/sfx"...(+1)`
```

首先，使用回報的 NeoVim 設定，在 Lua language server 中重現 issue 裡的 enum-alias 範例，重點關注診斷期間如何解析引號括住的成員內的 `#`。當包含 `#` 的完整字串仍然是 enum 成員，且所示的指派不再產生回報的型別檢查錯誤時，即表示完成。
