Autocompletion is not offered for a parameter with a `@class` type

Personne n'a encore pris cette issue.

### 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?

Completion

### Expected Behaviour

When using a defined class as the type for a parameter, the fields of that table should be offered as an autocompletion when calling the function.

For an example, using `@alias` works like so:

### Actual Behaviour

No autocompletion is automatically offered when using `@class` as the type for a parameter. If you press CTRL + Space, you can make the completions appear, but they will not appear automatically.

Nothing is offered:
Until I press CTRL + Space:

### Reproduction steps

1. Use the below code:
```lua
---@class Options
---@field page number
---@field active boolean

---@param opts Options
local function acceptOptions(opts) end

acceptOptions()
```
2. Move your cursor to line 9 (`acceptOptions()`) and place it between the parentheses
3. Enter `{` to start a table literal
4. No completions are offered
5. Press CTRL + Space and notice that the first 2 options are actually proper completions from the `Options` class. These should automatically be offered.

### Log File

_No response_

Aucun fichier source ni aucun test n’est nommé dans l’issue. Commencez par exécuter la reproduction Lua fournie dans l’extension VS Code et suivez le comportement de la complétion après avoir saisi `{` pour le paramètre `Options` ; c’est terminé lorsque les champs `@class` sont proposés automatiquement sans appuyer sur Ctrl+Space.
