[BUG] Docker Release Image incorrectly bundled default yml and entrypoint file

[peterzhuamazon]

We did not see this having issues due to 1.x/2.x and default is having nearly same content except a few comments in yml.

As for entrypoint file the 1.x docker is actually bundled with default entrypoint, which includes bunch of allowlist of parameters, that is why it is not seeing issues previously.

Example:
https://build.ci.opensearch.org/job/docker-build/3765/console
