doDevonCommand should use doFail instead of doAskToContinue

[hohwille]

This issue is about reconsidering this line of code:

ide/scripts/src/main/resources/scripts/functions

Line 328 in d72d893

doAskToContinue "Failed to run devon ${*} - do you want to continue?"

If doDevonCommand is called and fails it will ask the user to continue.
This currently made our build stalled as the automated tests ran into this situation and the build was waiting for user-input that could never happen.

We should question why this behavior has been introduced.
Maybe it makes sense if devon release calls other functions and the user might want to continue in some cases.
However, IMHO this is not a good default behavior and should only apply in very special situations.

Finally, if we keep interactive questions like this, we need to run all our tests strictly in batch mode.
Even better devonfw-ide could check if the environment can actually never provide user input (no tty present, ${CI}=true, etc.) and enable batch mode automatically in such case.

For the record:
These "special situations" are already using `doDevonCommandAndReturn":

ide/scripts/src/main/resources/scripts/command/release

Line 110 in d72d893

doDevonCommandAndReturn build release "${@}"

So IMHO there is no need left for this doAskToContinue.
PR #936 created.
