MonthYearPicker: Excluded/Disabled Months are able to be navigated to with keyboard

[ryantanrk]

Describe the bug
When a month year picker has excluded dates excludeDates, without any value selected, the date picker is able to navigate to the excluded month, but with value selected, we cannot navigate to the excluded month.

When that excluded month is selected, it throws an invalid time value error:

To Reproduce
Steps to reproduce the behavior:

1. Open calendar with a excluded month and selected is null
2. Use arrow keys to try and navigate to that excluded month
3. Excluded month should be pre selected (For invalid time value error select with Enter or Space and try to use the arrow keys again)
4. Select an available month with the keyboard
5. Open the calendar again
6. Try to navigate to the excluded month
7. Pre selection will stay the same

Expected behavior
Consistent behavior when there is a value selected and when there is no value selected. I suggest the date picker should skip over the excluded date when navigated to with the keyboard
