What this PR does / why we need it:
fix: revert alpine base image change to fix DNS issue

revert of #1175

On some k8s clusters with customer vnet setting, cifs mount cannot resolve DNS while nslookup works well, and switch to debian-base image works.

other reference: nodejs/docker-node#1030 (comment)

btw, though alpine is updating musl lib which could solve dns-over-tcp (on alpine 3.18), while it's still not suggested to use alpine image since we don't know whether there is other potential dns issue: https://news.ycombinator.com/item?id=35056594
