Render the "View Blame prior to this change" within the inline blame experience

Context

The current implementation of the "View blame prior to this change" which is attached on each line with previous history, needs to be rerouted to rendering within the new blame experience.

Details

Seems like the implementation generates the HTML on the backend.

We can either simply support this with a reroute of the link to the new blame experience.

Or work with the backend to provide the information of the rev/commit sha we should jump to and re-render the blame on that SHA. (in this case, we'd need to label backend and schedule capacity for this)
