Add Tab Support to InputNumber (within Datatable) (#3110)

* Add Tab Support to InputNumber (within Datatable)

When editing an inputnumber in the "cell" edit mode within a datatable, tab does not trigger the onCellEditComplete (or validators), because it is missing from the switch list. I found the same issue with the same solution in PrimeVue: https://github.com/primefaces/primevue/pull/1954/files.
