Image renderer plugin 3.4.2 appears to be incompatible with Grafana 9.0.3 Alpine Docker image

What happened: Grafana 9.0.3 in Alpine Docker image fails to start when Grafana Image Renderer is enabled. The latest version of the plugin right now is 3.4.2.

9.0.2 works. Ubuntu Docker image works. Alpine image is 3.15.4 in case of both 9.0.2 and 9.0.3.

How to reproduce it (as minimally and precisely as possible):

cd $(mktemp -d)
wget https://raw.githubusercontent.com/grafana/grafana/acf54905eeeb92cd692b006c1819fc3ecd623361/packaging/docker/custom/Dockerfile
docker build --build-arg GF_INSTALL_IMAGE_RENDERER_PLUGIN=true -t grafana-image .
docker run --rm  -e GF_LOG_LEVEL=debug grafana-image

The ld-linux-x86-64.so.2 and the symbol not found errors also appear in 9.0.2 and the plugin works, so I guess those are red herrings and we need a new plugin release?

Environment:

• Grafana Image Renderer version: 3.4.2
• Grafana version: 9.0.3
• Installed plugin or remote renderer service: Plugin
• OS Grafana Image Renderer is installed on: Ubuntu 22.04

With grafana 9.0.7 and renderer 3.5.0 I don’t have this issue anymore.
