Rename playbook parameter to playbookFile
To be consistent with Maven naming practices (e.g., pomFile), we should rename the playbook parameter to playbookFile. This not only reinforces it's type, but it also aligns it better with playbookProvider
, which is mutually exclusive with a local playbook file. We can keep playbook
as an alias, though we may consider reusing that parameter for another purpose in the future.
