Replaced the date picker

Using this date picker: https://material-ui.com/components/pickers/#datepickers

CSS API for date picker was pointed here: https://material-ui.com/components/pickers/#api https://material-ui.com/api/text-field/#css

For the components/elements that can't be selected using rules, we can use Nesting selectors. Refer here: https://material-ui.com/styles/basics/#nesting-selectors

Has not saved the date value yet, because we suppose to change a way to save and pass all the values. So, will add saving functionality after finish replacing Formik.
