fix(IdDocsValidation): replace Vue 2 @update:value with @update:modelValue on NcActionInput

NcActionInput changed its emit from `update:value` to `update:modelValue`
in @nextcloud/vue v9 (Vue 3). Replace @update:value with @update:modelValue
on the owner filter NcActionInput so the onFilterChange callback is triggered
when the user types in the filter field.
