Post History with Diff widget

Description

All https://devgovgigs.near.social/ posts store their editing history in a smart contract (https://github.com/near/devgigsboard/), but we currently do not display it. Please create a widget with a dropdown with timestamps and accounts corresponding to when and who edited a webpage. Criteria Resources

Acceptance criteria

When a timestamp is clicked, it should open the webpage with the post the way it looked after that edit. When selecting two timestamps (alternatively you can have a nicely designed diff button), it should open a diff window that shows what parts of the posts have changed between two selected timestamps. Quality of UI design and UX are the major factors in determining whether to grant this bounty. Please create them as separate widgets that we can later embed into https://devgovgigs.near.social/.
