fix: pipe workerIdleMemoryLimit to globalConfig

[backmask]

Summary

New argument workerIdleMemoryLimit did not get forwarded from package.json to the workers. This fixes it. Context: #11956 (comment)

Test plan

Tested manually, added a console.log in TestRunner::createParallelTestRun, saw an undefined workerIdleMemoryLimit without the fix. Works with the fix

The following entry has to be added to package.json to test the fix

  "jest": {
    "workerIdleMemoryLimit": "500MB"
  },

Ugh, almost same as #13105. Feels like we should have some tests it's properly threaded through 😅

This fixes the first issue (the flag having no effect). It does not fix workers being killed and not respawning. For the second bug, I haven't found a fix or if I have done a misconfiguration. I will let you know if I find anything!

Your analysis is mostly correct... The workers are being killed, they are respaning, the request to re-run the request is being sent then just nothing. The plot thickens.

{ limit: 200000000, childUsage: 238479704, restart: true, pid: 89632 }
{ preState: 'restarting', state: 'ok', prePid: 89632, postPid: 89655 }
RESENDING REQUEST [
  1,
  true,
  'worker',
  [
    {
      config: [Object],
      context: [Object],
      globalConfig: [Object],
      path: '/Users/paul/Documents/GitHub/brand-engine/src/common/helpers/express/__tests__/listenForStatusCode.test.ts'
    }
  ]
]

As for the config fix above, that works correctly and should be merged.

I currently have no idea why but this promise is not resolving in a worker that has been restarted.

I have a test case for the issue as part of a new e2e test.
#13107

I should've created one of these in the original PR and we wouldn't have had these issues.

Heading to bed now, tomorrow will be trying to figure out why it's misbehaving.

let's land this in the meantime as it's a correct tweak 🙂
