Fix ContinueTask user prompt for locales with uppercase yes (#1735)

* Fix ContinueTask user prompt for locales with uppercase yes

The yes/y strings have to be converted to lowercase to enable matching of
the user input converted to lowercase. Otherwise, locales with uppercase
yes/y strings (e.g., German: `Ja/J`) will never match.

* Addess linter issue

* Remove obsolete lowercase conversion
