[Time to Visualize] Library Notification Call To Action

[ThomThomson]

Now that the Library notification has the ability to 'unlink', it's important to update the copy to add a call to action

Current Wording

Suggested wording from product
"Editing the panel might affect other dashboards. To apply changes to this panel only, unlink it from the library before you edit"

@gchaps - I like the copy suggestion from product, do you have any input on this change?

@ThomThomson I think we can shorten this text a bit:

Editing this panel might affect other dashboards. To change to this panel only, unlink it from the library.

Thanks @gchaps, I've implemented that suggestion.
