assign-type-mismatch not reported for global values

Ninguém assumiu esta issue ainda.

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

NeoVim

### Which OS are you using?

Linux

### What is the issue affecting?

Annotations, Type Checking, Diagnostics/Syntax Checking

### Expected Behaviour

With a global table that has type-annotated fields, reassigning a field to an incorrectly-typed value should report `[assign-type-mismatch]`

### Actual Behaviour

No diagnostic is reported, even though autocompletion indicates that the type is understood by the server. Further, assigning a local variable to the global value and doing the same thing _does_ report the diagnostic correctly.

### Reproduction steps

```lua
---@class test
_G.test = {
---@type boolean
foo = true,
}
test.foo = 'bar' -- no error
_G.test.foo = 'bar' -- no error
local test2 = test
test2.foo = 'bar' -- [assign-type-mismatch]
```

### Additional Notes

_No response_

### Log File

_No response_

Comece executando a reprodução Lua fornecida e compare os diagnósticos para test.foo, _G.test.foo e test2.foo. Rastreie o caminho de verificação de tipos e diagnósticos para valores globais; considera-se concluído quando as duas atribuições globais reportarem [assign-type-mismatch] de forma consistente com o caso do alias local.
