fix: fix a version issue that happens on the newer builds of alpine-l…

…unix (#2063)

Originally, I stumbled on an error with `../src/pipeline.cc` where it complained about an invalid struct type.

After some searching I found the issue:
The current image used as base in the Dockerfile example links to an alpine-linux version **later** than 3.18, which has made changes in `libvips`, as discussed in this PR: [Link](nodejs/docker-node#2009)

The PR also mentions, that fixing the build to version 3.18 resolve the issue, which I also confirmed in my local setup when trying to deploy strapi through docker compose.
