Setting Array to the 'classes' prop leads to types mismatch error

[agantelin]

Describe the bug
As stated in the documentation (https://kyvg.github.io/vue3-notification/api/#props) the 'classes' prop can receive String or Array types. But in fact Array leads to types mismatch error:

[Vue warn]: Invalid prop: type check failed for prop "classes". Expected String with value "vue-notification,n-light", got Array

To Reproduce
Set the prop 'classes' to any array of strings:
<NuxtNotifications :classes="['vue-notification', 'n-light']" />

Expected behavior
Setting prop 'classes' to array of strings should adds all the classes listed in this array.

Additional context
There is the workaround: setting a list of classes separated by spaces.
<NuxtNotifications classes="vue-notification n-light" />
But this is not an Array type.
