考虑以下 Azure yaml 管道和模板，它们使用convertToJson函数将对象参数转换为 json 字符串：

parameters:
  - name: foo
    type: string
    default: 'b"ar'

trigger: none

pool:
  vmImage: 'ubuntu-latest'

variables:
  - name: foo
    value: 'b"ar'

steps:
  - checkout: none
  - template: /pipelines/steps/set-settings.yaml
    parameters:
      settings:
        fooLiteral: 'b"ar'
        fooParameter: ${{ parameters.foo }}
        fooCompiledVariable: ${{ variables.foo }}
        fooRuntimeVariable: $(foo)

模板/pipelines/steps/set-settings.yaml：

parameters:
  - name: settings
    type: object

steps:
  - script: |
      echo $SETTINGS
    displayName: 'Display settings'
    env:
      SETTINGS: ${{ convertToJson(parameters.settings) }}

运行管道时，为什么除了 之外所有值都会得到正确转义fooRuntimeVariable？
