ERESOLVE after upgrading from Ember 4.8 to 5.4

[paddor]

With the following dependency:

package.json:    "ember-flatpickr": "^4.0.0",

When running npm i:

npm ERR! code ERESOLVE

It looks like you might have to upgrade the peerDependency for Ember 5.x?

Sorry, my bad. I should probably use the current version...
