A simple way to fix the nonsense that is the github actions format.

pipeline-fix.ts

import { parseDocument, isMap, YAMLMap, Scalar } from 'yaml'

async function getInput(): Promise<string> {
  return new Promise((resolve, reject) => {
    let data = '';

    process.stdin.setEncoding('utf8');  // Optional: interpret as text

    process.stdin.on('readable', () => {
      let chunk;
      while ((chunk = process.stdin.read()) !== null) {
        data += chunk;
      }
    });

    // No idea what would cause this.
    process.stdin.on('error', (error) => {
      console.error(JSON.stringify(error))
      reject()
    })

    process.stdin.on('end', () => {
      resolve(data)
    });
  });
}

let doc = parseDocument(await getInput())
let jobs = doc.getIn(['jobs'], true)

let newJobList: any[] = [];
if (isMap<Scalar, YAMLMap>(jobs)) {
  for (let job of jobs.items) {
    let newObj = {
      ...(job.value?.toJSON()),
      jobName: job.key.value,
    }
    newJobList.push(newObj)
  }
}

doc.setIn(['jobs'], doc.createNode(newJobList))

console.log(JSON.stringify(doc.toJSON()))

What this does is an important job. It converts the yaml into JSON (much easier to deal with) and it turns the job list into an actual list. That is important as most languages do not retain an order for property maps.
