It is better to have multiline for annote the @overload

Nobody has claimed this yet.

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

Visual Studio Code Extension (sumneko.lua)

### Which OS are you using?

Windows

### What is the issue affecting?

Annotations

### Expected Behaviour

```lua
--- @overload fun(
--- x:number,
--- y:number,
--- width:number,
--- height:number
--- ):Object
```

### Actual Behaviour

```lua
--- @overload fun( x:number, y:number, width:number, height:number ):Object
```

### Reproduction steps

1. Go to '...'
2. Click '...'
3. See error '...'

### Additional Notes

Please adding this feature because some of my annotation is really really long.

Writing in one line makes unreadable and ugly.

Thanks much!

Reproduce the annotation behavior in the Visual Studio Code extension using the multiline and single-line @overload examples from the issue. Start by tracing how Lua annotations are parsed, then verify that multiline overload signatures are accepted and remain readable without breaking existing annotations.
