invalid signature of inject

[jacekkarczmarczyk]

Vue 3.0 https://github.com/vuejs/vue-next/blob/master/packages/runtime-core/src/apiInject.ts#L29):

export function inject<T>(key: InjectionKey<T> | string): T | undefined

Vue 2.x composition api (https://github.com/vuejs/composition-api/blob/master/src/apis/inject.ts#L35):

export function inject<T>(key: InjectionKey<T> | string): T | void;

void instead of undefined makes impossible to use non-null assertion operator

I've installed 0.5.0, still got wrong type.

This was merged after 0.5.0.

Well hopefully soon have a fresh release with this type correction and a lot more from #311
