BREAKING: Removed the following deprecated package commands:

• app:build - Use package build instead
• app:serve - Use package start instead
• backend:build - Use package build instead
• backend:bundle - Use package build instead
• backend:dev - Use package start instead
• plugin:build - Use package build instead
• plugin:serve - Use package start instead
• build - Use package build instead
• lint - Use package lint instead
• prepack - Use package prepack instead
• postpack - Use package postpack instead

In order to replace these you need to have migrated to using package roles.
