fix: types compatible with nuxt-property-decorator

[Kolahzary]

No more type errors for forced color mode on nuxt-property-decorator

import { Component } from 'nuxt-property-decorator'
import Vue from 'vue'
@Component({
  colorMode: 'light',
  ...
})
export default class LightModeForcedPage extends Vue {
 ...
}

Given error before this fix:

 Overload 1 of 2, '(options: ComponentOptions<Vue, DefaultData<Vue>, DefaultMethods<Vue>, DefaultComputed, PropsDefinition<Record<string, any>>, Record<...>> & ThisType<...>): <VC extends VueClass<...>>(target: VC) => VC', gave the following error.
    Argument of type '{ colorMode: string; layout: string; components: { ValidationObserver: ExtendedVue<Vue & { $_veeObserver: VeeObserver; $vnode: VNodeWithVeeContext; }, { ...; }, { ...; }, unknown, { ...; }>; ValidationProvider: ExtendedVue<...>; DatePicker: any; }; }' is not assignable to parameter of type 'ComponentOptions<Vue, DefaultData<Vue>, DefaultMethods<Vue>, DefaultComputed, PropsDefinition<Record<string, any>>, Record<...>> & ThisType<...>'.
      Object literal may only specify known properties, and 'colorMode' does not exist in type 'ComponentOptions<Vue, DefaultData<Vue>, DefaultMethods<Vue>, DefaultComputed, PropsDefinition<Record<string, any>>, Record<...>> & ThisType<...>'.
