Update production dependencies (remove Pikaday, bump Numbro, DOMPurify and momentjs)

[budnix]

Context

The PR updates dependencies. The changes:

• Remove pikaday (and its typings). The package was kept here only for compatibility reasons;
• Bump numbro to the latest version (2.1.2 to 2.5.0);
• Update core-js (update the babel config file to use the newer version);
• Upgrade dompurify (v2 to v3);
• Update momentjs to the latest version (2.29.4 to 2.30.1). The update fixes some bugs. After careful checking and making sure that the new version fixes the logic, I updated the tests;

How has this been tested?

I tested the changes locally.
