new: when validating a ref object update attribute path in data

[primalmotion]

It is convention that elemental.Error Data can hold a map[string]any or map[string]string that may have a key 'attribute' giving the attribute name to which the error relates to.

This patch adds a function that update the attribute key to hold the full path of the position of the error in the object.

For instance, if you miss parent.children[0].name that is required, instead of having the attribute key set to 'name' it will be set to 'parent/children/0/name'.

@chris-acuvity please test.

• point elemental to this branch in backend go.work
• make api in the backend
