maybe a little unit test ? to validate future non regression ?  As it's boolean it's more logical to use `&&` instead of `==` but you can keep it if you want.
Required properties should be listed first in Editor doc (webapp)
### Expected Behavior

Required properties should be listed first in doc for better visibility of what I should absolutely add to my task

### Actual Behaviour

Properties are listed as in POJO I guess

### Steps To Reproduce

1. Create a task with required & non-required properties (eg. https://kestra.io/plugins/plugin-azure/tasks/batch.job/io.kestra.plugin.azure.batch.job.Create.html)
2. job is listed after some non-required properties

### Environment Information

- Kestra Version: 0.8.0-SNAPSHOT
- Operating System (OS / Docker / Kubernetes): Mac
- Java Version (If not docker): 11


### Example flow

id: a-flow
namespace: some.namespace
tasks:
  - id: taskOne
    type: io.kestra.plugin.azure.batch.job.Create
