feat(dockerfile): add graph to Dockerfile

[gruebel]

By submitting this pull request, I confirm that my contribution is made under the terms of the Apache 2.0 license.

Description

• added a graph to Dockerfile with all official Docker instructions as resource_types without edges
• added one regular graph check CKV2_DOCKER_1 which ensures that sudo isn't used

ex.

checkov -d [path to test files] --framework dockerfile -c CKV2_DOCKER_1
