Description of the Change

Adds new Terms Picker component to allow editors to pick a single category from set of categories. There is similar existing component in core https://github.com/WordPress/gutenberg/blob/trunk/packages/editor/src/components/post-taxonomies/hierarchical-term-selector.js but it is a checkbox instead of radio picker.
