DAB Validation does not catch wrong references

[MeinAccount]

Describe the issue

Consider the following DAB definition

resources:
  schemas:
    test:
      name: test
      catalog_name: test
  volumes:
    ingest:
      name: ingest
      schema_name: ${schemas.test.name}
      catalog_name: ${schemas.test.catalog_name}
      volume_type: MANAGED

This definition is wrong, as one should be using resources.schemas.test.name instead of schemas.test.name.

Expected Behavior

Validation fails

Actual Behavior

Validation is successful, only failing on deploy

OS and CLI version

Using Databricks CLI v0.265.0 on Ubuntu 24.04
