Update version of jQuery

[hannalaakso]

jQuery is currently being included as a sub-dependency of this component via openregister-picker-engine which includes corejs-typeahead.

As jQuery 3.2.1 has reported medium severity vulnerabilities, jQuery should be updated to the latest version 3.6.0 which has no reported vulnerabilities.

The compiled files in dist/ should then be re-built and a new version released.
