add AlgoliaSearchBar component

[Baroshem]

Is your feature request related to a problem? Please describe.

Similarly to what I have created for the nuxt-newsletter, I think it would be beneficial to have an unstyled but working search bar component that users can easily use in their application without using the vue instantsearch.

Describe the solution you'd like
