Automatic doc generation builds incorrectly assumingly large types as a return value

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, Completion

### Expected Behaviour

```lua
---comment
---@param value any
---@return "boolean"|"function"|"nil"|"number"|"string"|"table"|"userdata"|"thread"
local function myAwesomeFunction(value)
return type(value)
end
```

### Actual Behaviour

```lua
---comment
---@param value any
---@return "boolean"|"function"|"nil"|"number"|"string"...(+3)
local function myAwesomeFunction(value)
return type(value)
end
```

### Reproduction steps

Copy the code
```lua
---
local function myAwesomeFunction(value)
return type(value)
end
```
execute autocompletion from `---`.

### Additional Notes

Probably not a very important issue.

### Log File

_No response_

Reproduce the issue in the Visual Studio Code extension using the Lua example and trigger autocompletion from `---`. Compare the generated `---@return` annotation with the full union shown in the expected behavior; done means large return types are no longer abbreviated with `...(+3)`.
