[fix] DatePicker component uses defaultProps which is to be deprecated and causes console warning.

[Steven7926]

ReactUSWDS Version & USWDS Version:

"@trussworks/react-uswds": "^9.0.0",
"@uswds/uswds": "3.7.1",

Describe the bug

When building a form using your component library I kept running into a console waring stating:

"Support for defaultProps will be removed from function components in a future major release. Use JavaScript default parameters instead."

Upon further investigation I found that this was coming from the DatePicker component. At the end of DatePicker.tsx you are using
DatePicker.defaultProps = {
minDate: DEFAULT_MIN_DATE,
}
to set a minimum allowable date for the datepicker component, this is trggering the warning.
defaultProps is also used in the Tooltip component.
To Reproduce
Steps to reproduce the behavior:

1. Create a page and use the datepicker and tooltip components
2. Render that page
3. Open dev tools in the browser and view the console
4. See error: "Support for defaultProps will be removed from function components in a future major release. Use JavaScript default parameters instead."

Expected behavior

No warning should appear in the console to prep your library for deprecating feature support.

@Steven7926 and @brandonlenz (saw you've reviewed some things recently) - put up a quick PR for this one in case anyone has cycles to review: #2949

Looks like workflows need approval from a maintainer as well.

A fix for this is now merged and I imagine will go out with the next release.
