feat: support Arguments for Lambda when query language is JSONata

[edvaldoszy]

When using JSONata as the query language, AWS creates the step definition with Arguments instead of Parameters.

Example:

Step name:
  Type: Task
  Resource: arn:aws:states:::lambda:invoke
  Output: '{% $states.result.Payload %}'
- Parameters:
+ Arguments:
    FunctionName: <function ARN goes here>
    Payload: '{% $states.input %}'

That leads to the error below

Deploying "project-name" to stage "staging" (us-east-1)
Layer sharp is already uploaded.
✖ Stack staging-project-name failed to deploy (7s)

Hello, any idea when this change will be released ?

[zirkelc]

@PaulBanusIAD that is up to @horike37

[zirkelc]

Hey @edvaldoszy I found one more mistake, please correct this then we can get this merged

[zirkelc]

I extended the test should support variable FunctionName to also include JSONata and noticed there is an issue with the resolved IAM template. Since JSONata uses the key FunctionName without .$ suffix, I had to re-order how this is checked. Now it first checks for JSONPath and JSONata strings and then goes to check for intrinsic functions
