Fix "cancel" as per current locale

[szepeviktor]

Currently with default locale "canceled" is a marked as a typo.

The forms of cancel in American English are typically canceled and canceling; in British English they are cancelled and cancelling.

en_us -> canceled, canceling
en_gb -> cancelled, cancelling

Thank you.

But

There are examples of cancelled in American use, and of canceled in British, so you needn’t feel bad about yourself if you mistakenly use the variant that is less common where you live

Sorry for the delay.

You mentioned "default locale". Without setting a locale, I do not see it corrected. Alternatively, 10 days before this post, you posted

Could you clarify under what conditions you are seeing what behavior?

That might be a mistake. Even v1.19.0 allows both versions.
