DatePicker unable to select minimum date in certain timezones

[nacydee]

Describe the bug
minDate is provided in format "yyyy-MM-dd", there seem to be some date conversions happening that block the minimum date from being selected in certain time zones. For example when minDate is "2021-01-01", a user with Mumbai (GMT+5:30) timezone will be unable to select 2021-01-01, but the minimum date they are able to select is 2021-01-02. At the same time a user in the Pacific Timezone will be able select 2021-01-01, but they will also have the option to select 2020-12-31 although the date will be invalidated.

To reproduce
Steps to reproduce the behavior:

1. Go to https://sap.github.io/ui5-webcomponents/playground/components/DatePicker/
2. Change the browsers timezone to Mumbai (GMT+5:30). In Chrome you can open devtools select Menu “⋮” > More tools > Sensors > Change location to Mumbai. Check timezone has been changed.
3. Scroll to the third example where min-date="1/1/2020". The earliest date you can select is 1/2/2020. Unable to select 1/1/2020.

Isolated example

Expected behavior
The minimum date should be available to select regardless of the timezone user is in.
