Issue : minimum and maximum validations do not work in RJSF JSON FORM DATE PICKER COMPONENT

This is an existing issue with the RJSF library itself.

• The RJSF schema expects minimum and maximum to be number.

• However, the html element with type = ‘date’ expects min to be a string of format ‘yyyy-mm-dd’ Check here

Case 1 : In the RJSF schema, if we pass minimum = dayjs().format(“YYYY-MM-DD”) i.e. a string. The datePicker works as expected but while submitting the form validation error is thrown

schema is invalid: data/properties/startDate/minimum must be number, data/properties/endDate/minimum must be number

Case 2 : If we try converting the minimum to number something like this dayjs().valueOf() -> then validation works fine but datePicker wont work as expected because min will be number and wont work on (Refer below screenshots)
