chore: consolidate promise resources finalisers

[kirederik]

as part of #90, we introduced more deterministic labels into the resources that get created when a promise is installed.

as part of this chore, let's consolidate the deletion of all Promise k8s resources within the Promise Controller into a single finalizer (i.e. Jobs, ServiceAccounts, ClusterRoles, ClusterRoleBindings, ConfigMaps, Works). Those resources should all have a kratix.io/promise-name that can be used.

🚨 This may introduce a breaking change, depending on how it's implemented
