add script and workflow to generate static info-page with mtinfo

[BuckarooBanzay]

This adds a workflow and script to generate a static info page with the mtinfo mod. The static page contains the node-previews as well as some additional infos like recipes, abm, etc. It is still in a rough state but pretty usable right now.

• Mod: https://github.com/BuckarooBanzay/mtinfo/
• Example: https://mt-mods.github.io/technic/#/mods/technic/items

Leaving this here as draft as it needs the "github-pages" setting enabled in the repository-settings and i think i'll add some more polish to the mtinfo mod.
