Describe the bug
The put step allows a user to (optionally) specify the inputs key as "all", "detect", or a list of resources. If the user provides "all" or "detect" then the extension displays the error

Expecting a 'Sequence` but found a `Scalar`

To Reproduce
Create a job with a put step and specify the inputs key as "detect"

Sample

jobs:
- name: example-job
  plan:
    - put: example-resource
      inputs: detect
