For this issue, the front-end needs to abandon two APIs:

• v1alpha2/tojenkinsfile
• v1alpha2/tojson

then you could update the Jenkinsfile with JSON or raw format with the following API. Please feel free to read more details about this API from the swagger.

• /v1alpha3/devops/{devops}/pipelines/{pipeline}/jenkinsfile

you could get the JSON format of the Jenkinsfile from annotation with key pipeline.devops.kubesphere.io/jenkinsfile

add jenkinsfile.validate to annotation valid values are success and failure

if failure, show like this:

if there is no jenkinsfile.validate, due as success.
