GraphViz Diagrams are not rendering correctly in version 0.1.1

[iain-b]

It appears that GraphViz diagrams do not render correctly in the current version. They render correctly with older versions e.g. 0.0.16.

Steps to reproduce

• Checkout / navigate to these files https://github.com/backstage/techdocs-container/tree/main/mock-docs
• Run techdocs-cli serve
• Navigate to http://localhost:3000/docs/default/component/local/#the-attack-plan

Workaround

• Diagrams render correctly using the older docker image techdocs-cli serve -i spotify/techdocs:v0.2.2 (which corresponds to v0.0.16)

Caveats I'm assuming the issue is here an not to do with the graphviz binary( I haven't checked if the installed version is different).
