Remove popper js from importmap.rb

To the best I can tell it isn't used.

popper.js is a peer dependency of bootstrap. https://getbootstrap.com/docs/5.3/getting-started/javascript/#dependencies it looks like drop-downs, popovers and tooltips require this.

If I'm not mistaken, all of those BS components are opt-in. And I don't see any indication that we've opted in to any of them.

@justinlittman I don't see anything about opting-in here: https://getbootstrap.com/docs/5.3/components/dropdowns/ All you have to do to opt in is to add the attribute data-bs-toggle="dropdown" to a DOM node.

Dropdowns, popovers, and tooltips aren't used in purl. However, since it is a tiny library, I'm going to close.
