MINOR: Fix CDS in docker image (#15771)

Due to difference in packages present when jsa files were generated and when docker image is generated, there is a log on starting docker image.

[0.001s][warning][cds] The shared archive file has a bad magic number: 0

There is no functionality impact, only startup time is higher because of this issue.

This PR fixes the warning and improves startup performance of the docker image
