Add schema/v1/steps.json for CI use
There are 3 entry points to the step runner schema:
- The spec document in a
step.yml
file. This is validated against thespec.json
schema. - The definition document in a
step.yml
file. This is validated against thedefinition.json
schema. - The invocation of steps in a
gitlab-ci.yaml
file. This one needs a schema file.
This change adds the missing schema for the CI use case.
