Render blame info in the Source Viewer (all supported languages)

As part of rendering Blame file information within the Blob viewer frontend app we should ensure the Blame Info Vue component is rendered in the Source Viewer component.

In #425267 (closed) we implemented a way to render blame information in the Source Viewer when viewing JSON files.

This issue is about expanding the feature to other languages too.

Once #415753 (closed) is done the blame information should be rendered for other languages too.
Another way to make it work is to add the logic for fetching/rendering blame information to source_viewer.vue. Note, the source_viewer.vue will be replaced by source_viewer_new.vue once #415753 (closed) is done.
