Expose Date instead of Dayjs instance

[vasilii-kovalev]

Now

In some cases (like filter property in DatePicker component) a Dayjs instance is provided for end-users for dates filtering. It leads to the following problems:

1. Necessity to learn a new syntax, even though the project may not use Day.js. For example, we use date-fns, which works with the native Date objects
2. It exposes the implementation details. Each time the implementation (approach/library to work with dates) changes, it will be a breaking change for end-users

To Do

1. Expose Date instead of Dayjs instance in all places end-users can use it. Since Dayjs is an implementation detail, which I talked about above, right now it will be a breaking change
