Contributor guide

Research direction
Follow the existing pattern of validators in internal/validators and internal/functions packages. Copy the structure of a similar validator (e.g., label value) and implement label key. Add corresponding tests. Then register in registry.go, create documentation in examples/functions/label key/function.tf, and update the docs table with make docs. Finally, add an integration test in integration/main.tf.
