Monitors logic appears throws error when config.apiKey is present

[tmadej]

When trying to deploy with monitors enabled, config.apiKey present & test mode off, I found that this plugin was throwing the below error:

Environment: darwin, node 18.17.1, framework 3.34.0 (local) 3.33.0v (global), plugin 6.2.3, SDK 4.3.2
Docs:        docs.serverless.com
Support:     forum.serverless.com
Bugs:        github.com/serverless/serverless/issues

Error:
Error: When `monitors` is enabled, `DATADOG_API_KEY` and `DATADOG_APP_KEY` environment variables must be set.

When reviewing the logic for this, I found that the logic is slightly off. I cleaned it up in the below patch and it seems to be working as expected now:

Hi @tmadej, thanks a lot for opening this and testing out the patch

IIUC the config.testingMode === false && config.integrationTesting === false fixes the issue but I think the nested conditional needs a slight tweak to still error if only one of the API key or the app key is present. We would welcome a PR or we can work on one and update you here

Hey @tmadej,

I'm revisiting this, but there has been a couple releases since this issue was created. Is the issue persisting to this day? I'm not sure I understand what might be the issue. Happy to raise a PR to fix the problem. Could you share a reproduction case? Thanks!
