Runner registration API has been deprecated and needs to be updated

[Baibhav168]

Bug
API to register a new self-hosted-runner has been updated, and corresponding change in new runner registration is missing.
Earlier it used :
https://github.com/actions/runner/blob/main/scripts/create-latest-svc.sh#L132
export RUNNER_TOKEN=$(curl -s -X POST ${base_api_url}/${orgs_or_repos}/${runner_scope}/actions/runners/registration-token -H "accept: application/vnd.github.everest-preview+json" -H "authorization: token ${RUNNER_CFG_PAT}" | jq -r '.token')
to generate a token .

However new API looks like this:
curl -L -X POST -H "Accept: application/vnd.github+json" -H "Authorization: Bearer ${RUNNER_CFG_PAT}" -H "X-GitHub-Api-Version: 2022-11-28" https://${base_api_url}/${orgs_or_repos}/${runner_scope}/actions/runners/registration-token

To Fix
https://github.com/actions/runner/blob/main/scripts/create-latest-svc.sh#L132 needs to be updated with the new curl cmd

Raised PR for the fix: #3916

Our self-hosted runners suddenly stopped working today, and while investigating the issue I stumbled upon this thread. When was the API deprecated? Could it affect existing runners? We haven't touched our configs in months

Yurii Shylov:
Litmus test: If your existing runner is showing idle/active in the github repo settings -> ... -> Runners. Then its good, otherwise if it is showing offline, you need to use the updated API to re-authenticate your self-hosted runner.

Our issue was caused by a different thing. Apparently GitHub recently increased JIT configs for the runners to exceed 4 Kb, and it stopped fitting into SSM parameters. It was already fixed here: github-aws-runners/terraform-aws-github-runner#4613
