Validation script argument handling inconsistent with readme documentation

[rosskettle]

Expected Behaviour

JS validation script will run as documented in readme npm run validateFile ./schema.yaml <OpenAPI path>

Actual Behaviour

Fails due to mismatch between documentation and how args are handled in the code

Reproduce Scenario (including but not limited to)

try running the script as documented

Steps to Reproduce

Platform and Version

Sample Code that illustrates the problem

validateFile(process.argv[1], process.argv[2])
should be
validateFile(process.argv[3], process.argv[2])
if it is to be consistent with docs. (wrong number arg numbers and out of order)
