[BUG] IntegTest report yml does not correctly include node information and numbers

[peterzhuamazon]

Using CCR as example as it has 4 nodes, id-0 to id-3.
https://github.com/opensearch-project/opensearch-build/blob/2.16.0/manifests/2.16.0/opensearch-2.16.0-test.yml#L46-L57

However, as you can see in the test-report.yml in this run:
https://build.ci.opensearch.org/job/integ-test/8503/
https://ci.opensearch.org/ci/dbc/integ-test/2.16.0/10154/linux/x64/tar/test-results/8503/integ-test/test-report.yml

Only id-0 and id-1 are there while others are missing.

Mainly due to this section of hardcoding:
https://github.com/opensearch-project/opensearch-build/blob/2.16.0/src/report_workflow/test_report_runner.py#L167-L170

We need to dynamically read through folders and find the ids, instead of hardcoding in the python code.
Per the original review comment right here: #4352 (review)

Thanks.
