Many changes to the Zarf schema are coming before v1.0. The changes in this schema are described in #2600. Before we release the v1 schema we will release a v1beta schema. Functions in Zarf will be written to accept the newest schema but there will be a translator that will change an object of v1alpha1 into a object of the latest schema. This will involve refactoring the new api/v1alpha1 package so it is comprised only of the objects making up the Zarf package schema.

General flow of work:

• Create v1beta1 schema according to chore: schema adr #2600
• Create translator function between v1alpha1 and v1beta1 objects
• Create zarf dev migrate-schema command
• Replace internal Zarf functions to use the v1beta1 objects
• Allow users to create v1beta1 packages
