Add document meta_info representation to jinabox front-end

[chakrakan]

For the Jina AI hackathon, I wanted to see if there was a way to add decoded document meta_info onto the front-end portion of the static Vue appl that was supplied within the mutlires-lyrics-search example.

Based on a conversation with @nan-wang, it would seem that this feature doesn't currently exist, therefore, creating this issue to track this feature request.
