[fix] client/simple: add missing "swiped-events" devDependencies (import)

In commit 1a3543d4b in PR-4284 [1] the swiped-events [2] were forgotten to be
migrated.  In this patch, the event library is added to the ``devDependencies``
and imported by::

    import "../../../node_modules/swiped-events/src/swiped-events.js

[1] https://github.com/searxng/searxng/pull/4284
[2] https://www.npmjs.com/package/swiped-events
