since milvus's build procedure is in the responding docker enviornment,
this procedure does not bind with particular host os, in turn it allows
milvus build on any os , including latest ubuntu os
background:
our self hosted runner is only using ubuntu-latest os
benefit:
make this github workflow obtain the resource from the self-hosted
runner
