Add a indicator to the node upgrade status page for amendment blocked nodes (Version 1.5.0)

[shortthefomo]

Im unsure which is preferable to indicate what nodes are at risk of being amendment blocked or simply showing the ones that are amendment blocked the latter is sufficient as well.

would assume a RED dotted line or a shaded area to show the effected nodes that are no longer part of the network would be wonderful.

as of right now any node under 2.1.0 is amendment blocked, we are unable to easily see this on the page.

Thanks for the suggestion! I think it would be an useful feature. Will put it in the backlog as some design considerations need to happen before implementation
