Doesn't work on `Ember 5`

Clicking on `` on an `Ember 5.4` SPA (`Node 18.13`) has no effect, the component is completely inactive.

I realised that it is probably because of https://github.com/adopted-ember-addons/ember-pikaday/issues/550

And since that fix has yet to be released for some reason, I installed the commit containing the fix directly:

```
// package.json

dependencies: {
......,
....,
"ember-pikaday": "github:adopted-ember-addons/ember-pikaday#9471789a52dd6b3ed133df6d7834dfbfb010acb8"
}
```

Now when I run `ember s` the build breaks with:

```

```

Reproduce the failure with Ember 5.4 and Node 18.13 using the pinned 9471789a52dd6b3ed133df6d7834dfbfb010acb8 dependency. Inspect the ember-pikaday dist tree and @embroider/addon-shim treeForApp, focusing on the missing dist/_app_/components/pikaday-input.js path. Done means ember s builds successfully and PikadayInput responds to clicks.
