Checker mergequeue compatibility

[snowystinger]

Description

This started as a PR to update the code for the cla bot to support the merge queue feature. That was accomplished by adding some logic and new paths in 'checker.js'

However, in the course of this, we found that the version of node that this code relied on was a deprecated/removed environment in adoberuntime. So I bumped the node version to 18, which also included changes to the API as native support for fetch became a thing.

Unfortunately, the test runner was not supported on newer Node versions and it was written in a (now) less popular testing framework, so I moved us to a more modern version of jest and updated all the unit tests as well.

codecov's tool also wasn't supported anymore, but since this project doesn't need a lot of development, I figured it was ok to omit this for now since it's still reported in the CI logs themselves.

In the course of trying to deploy the changes, we also discovered that Travis CI is no longer supported, so I had to move us to GithubActions. During this, we didn't have the secrets for the integration test accounts anymore. I attempted to create new accounts, however, Github has changed some policies and will lock the accounts, any special requests for the accounts to be unblocked result in temporary reinstatement, then they become locked again.
As a result, I've stopped running the integration tests for now.

We actually don't wanna call set_green_is_bot because this handles when a PR is opened by the bot, and will end up giving back this result, like what happened here:

Pull request issued by a bot account, carry on.

Instead, we should add a dedicated, but similar function, like so:

async function set_green_has_signed_cla (ow, args) {
  let result;
  try {
    result = await ow.actions.invoke({
      name: utils.SETGITHUBCHECK,
      blocking: true,
      result: true,
      params: {
        installation_id: args.installation_id,
        org: args.org,
        repo: args.repo,
        sha: args.commit_sha,
        status: 'completed',
        start_time: args.start_time,
        conclusion: 'success',
        title: 'CLA Signed',
        summary: 'A Signed CLA has been found for the GitHub.com user ' + args.user
      }
    });
  } catch (e) {
    return utils.action_error(e, 'Error invoking setgithubcheck when CLA was found.');
  }
  return {
    statusCode: 200,
    body: result.title
  };
}

Once we add the set_green_has_signed_cla function, we can replace the lines below with the following (198-222):

const check = await set_green_has_signed_cla(ow, args);
return check;

hopefully turn off travis check

Looks good, thank you! Just one trivial change.
