Exact classes can have fields injected when used as parameters to funcitons

Nadie ha tomado este issue todavía.

Love the new exact class! When using it though, I noticed that I could still 'inject' fields into an exact class when it is used as the input to a function. Example:

```
---@class (exact) TestClass
---@field public a number
---@field public b string
---@field public c boolean

---@param test_param TestClass
local function test(test_param)
end

test({a = 1, b = "2", c = true, d = 4})
```
causes no error.

I am not sure if this is intended or not, but I would expect to get an warning like: ```Fields cannot be injected into the reference of `TestClass` for `d`. To do so, use `---@class` for `test_param`.Lua Diagnostics.(inject-field)``` here.

Reproduce el fragmento de Lua proporcionado en lua-language-server e inspecciona el manejo de exact-class para la comprobación de tipos de los parámetros de función. Se considera terminado cuando pasar un campo d adicional a TestClass produzca el diagnóstico inject-field solicitado, mientras que los campos declarados a, b y c sigan siendo aceptados.
