Conditionals cause pipeline.yml to fail validation

[r6e]

Problem

Using a conditional in a pipeline.yml file causes validation to fail with the following message: Property if is not allowed.. Shown here using the example from the Buildkite documentation, Using Conditionals:

Suspected Cause

It appears as though the schema does not currently support the if property. The schema.json does not have any attribute "if" within the commandStep.

Conditional properties were introduced approximately three months ago, so it seems likely that the schema simply has not yet been updated.

Suggested Fix

It seems likely that the fix will be similar to that in #4. This case may be simpler, as the documentation indicates only strings are supported by this property.

Any chance this might have been fixed by #6? It was just merged this morning.

@nchlswhttkr Looks like the actual merge took place almost exactly 5 minutes after I submitted this. Fastest turnaround on an issue ever 😄 Thanks for handling; much appreciated.
