Retry code coverage upload on failure (#3242)

### Description
Noticed in several results of

https://github.com/opensearch-project/security/actions/runs/5978371801/job/16220344142?pr=3123
that the code coverage upload had failed silently, and the annotations
make it look like many tests were not executed. Since in this job there
were 9 failures at the same time, adding retry mechanism as well to
prevent blind restarting of workflows.

### Additional background
