Change jQuery-Timepicker-Addon to another one

[htdat]

Coming from here https://github.com/Automattic/Edit-Flow/pull/649/files#r645456693

Info

This is a library and it's being used for the Date field in Editorial Metadata module - related PR #169
We can see it in action when editing a post (see screenshots below).

The plugin author no longer maintains it https://github.com/trentrichardson/jQuery-Timepicker-Addon/

Expected/Desired Behavior

We replace this jQuery library with another library or even with a Gutenberg component.
E.g: WordPress core has this component https://developer.wordpress.org/block-editor/reference-guides/components/date-time/
