Required modules' returns' types are wrong when more than a single value is returned

还没有人认领这个 Issue。

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

Visual Studio Code Extension (sumneko.lua)

### Which OS are you using?

Windows WSL

### What is the issue affecting?

Type Checking, Diagnostics/Syntax Checking, Libraries

### Expected Behaviour

First type should be a number, second - a string, third - a boolean

### Actual Behaviour


### Reproduction steps

main.lua
```lua
local number, string, boolean = require "required"
```
required.lua
```lua
return 1337, "string", true
```

### Additional Notes

_No response_

### Log File

_No response_

使用 main.lua require required.lua 来复现该报告，其中模块返回 1337、"string" 和 true。跟踪语言服务器中对 require 返回类型的处理，并验证三个被赋值的变量分别被推断为 number、string 和 boolean，且诊断结果正确。
