Set standard name for Cancel button, to align translations

[CarlosGS]

Breaking change

Proposed change

From a brief discussion in "Lokalise->Polymer frontend" for ui::panel::lovelace::editor::save_config::cancel

The original english text for the buttons is "Never mind" and "Take control".

Desired action for "Never mind" is to Cancel and close the prompt, however:

• Spanish translation was "No importa", in context "Sure, I don't mind" (!!)
• Default french translation was cheesy: "Oublie ce que j'ai dit, c'est pas grave" / "Forget what I just said, it is not important" 😄

From Dannie Rothman at Lokalise:

I Agree, Danish, Swedish and Norwegian also ends up as something like "Forget it" or "Not really" - i changed the Danish version to something matching "Cancel"

Proposed PR change is "Never mind" becoming "Cancel" to make it more intuitive and standard UI, aligned across languages.

More examples of the issue:

Yesterday I changed the spanish translation to "Mejor no", which is the closest expression I could find to accurately replace "Never mind" in the same context. But the edit has been reverted to "No importa" without realising of the context. This confusion can easily happen with any language, hence the suggestion to use "Cancel".

Latin spanish uses "Olvídalo" / "Forget about it", which is OK, but still feels a bit orthopedic.

Valid point 👍

We have common translation for cancel: ui.common.cancel

There you go, thanks for the tip @bramkragten! :)
