* Check SVG optimization in the tests CI workflow with SVGO
Previously it was only recommended by the documentation that SVG images should be optimized using [SVGOMG](https://github.com/jakearchibald/svgomg), the web GUI version of https://github.com/svg/svgo (CLI)
Now all SVG images are optimized, and optimization is mandatory enforced by the tests CI workflow.
\+ SVGs are sanitized of potentially malicious JS code using the https://svgo.dev/docs/plugins/removeScripts/ plugin
* Output prettified SVGs instead and remove unchanged files from stdout
