Wrong import URL in plugin usage guides

[madmini]

Plugin usage guides contain broken import urls that are missing the plugin subdirectory. For instance:

// wrong url from https://github.com/Shopify/draggable/tree/main/src/Plugins/Snappable#usage
import Snappable from 'https://cdn.jsdelivr.net/npm/@shopify/draggable/build/esm/Plugins/Snappable.mjs';
// should be:
import Snappable from 'https://cdn.jsdelivr.net/npm/@shopify/draggable/build/esm/Plugins/Snappable/Snappable.mjs';
