What this PR does / why we need it:
fix: upgrade base image to alpine 3.18 to fix DNS issue

tricky thing is that nslookup works inside the driver with alpine 3.15 image, but cifs mount returns dns resolution error, return error msg:

Output: mount error: could not resolve address for xxx.file.core.windows.net: Unknown error

https://www.msn.com/en-us/news/technology/alpine-linux-318-fixes-dns-over-tcp-issue-now-ready-for-all-the-internets-problems/ar-AA1bfaqi#:~:text=For%20many%20years%2C%20and%20by%20design%2C%20Musl%20did,meaning%20that%20it%20also%20works%20in%20Alpine%203.18.

The latest update to the ultra-lightweight Alpine Linux distro, as widely used for hosting Docker containers, fixes an important issue.…

There are many relatively small new features in Alpine 3.18, but one of them, while niche, could prove significant. One of several unusual things about Alpine Linux is that it doesn't use glibc, the standard C library that is the basis of almost all other Linux distros. Instead, Alpine is based on the smaller, lighter Musl libc.

For many years, and by design, Musl did not support DNS over TCP, only over UDP.

This has caused some Alpine users much consternation, and that has led some people to turn against Alpine. Well, no more: DNS over TCP is now supported in Musl 1.2.4, meaning that it also works in Alpine 3.18.
