Fixed page reload issue and date time picker render

[arunapa]

Issue: 1) DateTimePicker widget type does not render correctly
2) After submitting the metadata definition, empty page is loaded

Fix: 1) Migrate DateTimePicker away from @mui/lab, added Dayjs package as per MUI development guide

I tried adding metadata definition of type 'dateTimePicker'. It doesn't get created. I see this error on backend.

[ddey2]

metadata of type 'datetimepicker' is not created

[arunapa]

Note: Blank page issue was found to be related to the error reported in #217 , caused by an incorrect react state assignment, which I have corrected now

Datetime picker worked for me. Maybe try npm install?

I can create an definition of date time; but somehow i cannot update it

TypeError: descriptor 'time' for 'datetime.datetime' objects doesn't apply to a 'str' object

[longshuicy]

in metadata.config.tsx i think
~~ ~~"date": "Date",~~ ~~"time": "Time",~~ ~~
should just be
~~ ~~"datetime.date": "Date",~~ ~~"datetime.time": "Time"~~ ~~

Looks good.
