chore: Added some delays to docs publishing

[jsumners-nr]

After adding verbosity to docs gen (https://github.com/newrelic/node-newrelic/actions/runs/8145456792/job/22261755414) it looks like some operations are happening out-of-order (it could just be the way GitHub Actions records the logs, though). This PR adds some delays to try and solve that problem.

I'm not sure this is necessary. I think it's just how GHA buffers and outputs stdout and stderr
