fix(input-date-picker): apply default numbering system to avoid browser inferring from locale (#7682)

**Related Issue:** #7529 

## Summary

This applies our default numbering system to `input-date-picker`'s date
formatting.

### Notes

* Existing screenshot tests cover these changes.
* Firefox and Safari will now use `latn` as the default numbering system
when formatting the selected date when not explicitly specified.
