MenuToggle - add aria-invalid and aria-autocomplete

Describe the enhancement or change
Per https://github.com/patternfly/patternfly/issues/6562#issuecomment-2839684312:

• MenuToggle should be updated to apply aria-invalid="true" when the status is danger for non-typeahead/plain toggles (basic toggles and split button toggles). If there are any typeahead examples showing status, those should be updated to apply the aria-invalid to the input element.

• For typeahead variants, examples and templates should be updated so that aria-autocomplete="list" is applied to the text input being used as the typeahead input.

Is this request originating from a Red Hat product team? If so, which ones and is there any sort of deadline for this enhancement?

Any other information?

Jira Issue: PF-1732

Inizia con il componente MenuToggle, i relativi esempi e template, concentrandoti sulle varianti di base, split-button e typeahead. Aggiorna gli elementi renderizzati pertinenti in modo che lo stato danger esponga aria-invalid e gli input typeahead espongano aria-autocomplete="list"; il lavoro è completato quando gli esempi e il comportamento del componente riflettono questi attributi.
