Correct error message infos for "auto-cancel-after-failures"

[MikeMcC399]

Issue

1. The error message heading --auto-cancel-after-failures must be a integer or false contains a grammatical typo "a integer".
2. The text for the error message You passed the --auto-cancel-after-failures flag for a run that is already in progress contains a typo "takes precedent".

Change

In the above error message sections:

1. Change the error message heading to read "--auto-cancel-after-failures must be an integer or false"
2. Change "takes precedent" to "takes precedence" (see https://www.merriam-webster.com/dictionary/precedence)
