FIX: Fix broken translation in tags input field objects setting editor (#26340)

Why this change?

When a property of `type: tags` is required, we should be displaying the
"at least 1 tag is required" validation error message when there are no
tags selected in the `TagChooser` compoment. However, we were passing
`this.min` as the `count` attribute when generating the translation
string which is incorrect as `this.min` is not always set.
