Date picker - Keyboard doesn't open when clicking text field

Describe the bug
When clicking the text field on the DatePicker or DateTime picker, the keyboard doesn't open.

Component
SDC gallery app

To Reproduce
Steps to reproduce the behavior:

1. Go to SDC catalog app
2. Click on Date picker
3. Click on text field (not the calendar icon)

Expected behavior
The expected behavior is that manual keyboard based entry should be possible. We show a date format and only allow numerical date entry.

@aditya-07 disabled this in a previous PR. the reason was that we do not have a good way of ensuring the user enters well-formed date time string and validating it. at the moment, the dialog opens if the user clicks the icon. we do need to eventually re-enable this. but we do need to look into a solution that actually works.

Team discussion:

• Open keyboard (no dialog opens) when pressing input box (not the calendar icon)
• Validate using android system date format.
