[M] Add datepicker/rangepicker to Form Engine V2

[cameronpettit]

Forms Engine V2 does not yet have a datepicker/rangepicker. Many UI designs for data register necessitate a datepicker. Instead of implementing individual datepickers every time they are needed in the UI, we can implement a universal, reusable datepicker via the Forms Engine

Acceptance Criteria

• Datepicker/Rangepicker added to Forms Engine V2

Notes

Testing can take place via UI tickets Daniel is working on currently (reference tickets)

• date picker exists in https://github.com/bcgov/parks-data-register/issues/132 https://github.com/bcgov/parks-data-register/issues/133 https://github.com/bcgov/parks-data-register/issues/30

There's a github.io page that can be used for testing where you can out every combination of form that you can have in the github.io page; you can click through and see how it will be implemented (connect with Cam if you need further info).
