Add the DynamicPayloadModal to post the dyanmic_payload

[noahingh]

The UI allows you to dynamically insert a payload value if the dynamic_payload field is enabled. The UI for the example YAML is as below:

예제

envs:
  - name: dev
    auto_merge: false
    required_contexts: []
    dynamic_payload:
      enabled: true
      inputs:
        foo:
          type: select
          options:
            - one
            - two
          description: 'foo'     
          required: true
          default: 'one' 
        bar:
          type: string
          required: true
          default: 'baz'
        qux:
          type: number
          default: 0
