build(codegen): fix cmd-api-server .jar download race condition - again

[petermetz]

Description

The .jar download mechanism and the warm-up script has gotten us far but now the cmd-api-server package's interfering with it. Most likely because that package declares the open api generator as a dev dependency on it's own and that is causing it to not use the same installation of the same package from the root node_modules and that's why it ends up re-downloading the .jar file. This is just a theory for now but an initial glance at the log file (attached below) seems to support this theory as does the fact that the past 3 times when I observed this crash on the CI it was always the cmd-api-server package causing the problem instead of it being randomly distributed among the packages like it was before.

Solution ideas:

1. Use the --top-level flag of the yarn CLI to force the usage of the root level node_modules directory's .jar file
2. Refactor the code so that the warm-up script copies the .jar file to all the locations where it's needed (e.g. all the package directories node_modules subfolders.)

Acceptance Criteria

1. Race condition in the codegen script is eliminated.
2. No complicated logic has been introduced to fix it.

fixed by: #3289 and also tested 10 times while also limiting RAM to 7GB and vCPU cores to 2 and is running successfully.
