feat(ticdc): modify kafka, pulsar and storage prow-jobs (#3461)

This PR finalizes the setup for the `pull-cdc-kafka-integration-light`,
`pull-cdc-pulsar-integration-light` and
`pull-cdc-storage-integration-light`, but remains the `optional` flag in
`pull-cdc-kafka-integration-light` and
`pull-cdc-pulsar-integration-light` due to some unstable test cases.
