Provisioner API: Invalid yaml is returned if a job starts with an indent

Not sure exactly what the problem here is - but basically this job:

  function isNonEmptyString(v) {
    return typeof v === 'string' && v.trim().length > 0;
  }

Creates invalid yaml in the provisioner, which makes openfn pull break

To reproduce:

• Make sure you have CLI at least 1.19.0 installed (run openfn version to check)
• Create a folder called indent-test on your machine
• Inside, create a .env like this:

OPENFN_API_KEY=<your key>
OPENFN_ENDPOINT="https://app.staging.openfn.org/"

• Run openfn pull 3b1193b8-fb92-4c3d-9053-71f38bfc2e1f --log debug
• You'll get an error like SPEC_ERROR: All mapping items must start at the same column at line...
• To see the raw yaml, follow the stack trace to open up index.js at extractJobsToDisk and add this code at the top of the function

const fs = await import('fs')
fs.writeFileSync('project.yaml', specBody)

That will output project.yaml for you to inspect. Paste the output into a yaml validator and it'll throw

Start in index.js at extractJobsToDisk and reproduce with openfn pull 3b1193b8-fb92-4c3d-9053-71f38bfc2e1f --log debug using the provided indented function. Inspect the generated project.yaml with a YAML validator and trace how the job text is assembled. Done means the generated YAML remains valid and openfn pull completes successfully.
