Generics in nested functions don't work for some annotations unless there are no arguments passed

### 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

passing an argument should have no effect, and the types of nested functions should be resolved correctly
some examples:
```lua
---@generic T
---@param arg T
---@return fun(): fun(): T
local function POOL1(arg) return function() return function() return arg end end end -- implementing the function makes no difference for the typing
local func1 = POOL1(5.2) -- type is `fun(): fun(): number`
local func2 = func1(4) -- type should be `fun(): number`, instead it's `fun(): ` with an unresolved generic
```

```lua
---@class POOL2: { EnumerateActive: fun():(T, fun():T)) }
---@type POOL2
local headerPool = {}
local number, func = headerPool:EnumerateActive()
-- number type is `number`
-- func type should be `fun(): number`, instead it's `fun(): ` with an unresolved generic
```

```lua
---@alias POOL3 fun(arg: number): T, (fun():T)
---@type POOL3
local getPool
local number, func = getPool(3)
-- number type is `number`
-- func type should be `fun(): number`, instead it's `fun(): ` with an unresolved generic
```
all 3 examples work fine if you don't pass any argument

### Actual Behaviour

when an argument is passed to the outer function, the inner function doesn't have the generic resolved
if no arguments are passed (i.e. `headerPool.EnumerateActive()`), then they _are_ resolved properly
the type of the argument makes no difference, and annotating the function as accepting an argument also makes no difference

interestingly, when hovering over the function itself, the tooltip does show the correctly resolved types

### Reproduction steps

copy the provided snippets, and check which types the variables resolve to

### Additional Notes

Tested on both VSCode and Jetbrains IDEs
The example is contrived, my real usecase is to annotate an object pool class, that allows you to acquire objects of a given (generic) type, and allows iterating over them.

I know this has worked in a past version, though I don't remember how long ago that was (several weeks or months most likely)

### Log File

_No response_

首先重現提供的三個 Lua 註解範例，並檢查外部函式接收引數時巢狀泛型型別的解析方式。將推斷出的型別與無引數情況及預期的 hover 結果進行比較。完成的標準是三個範例都能將其內部函式解析為具體型別，例如 number，同時維持現有的正確行為。
