Add cursemaven maven coordinate to file details

https://www.cursemaven.com/ is a service for depending on Curseforge mods you might be familiar with. However, getting the maven file coordinate is a little bit annoying. Not hard, the project ID is listed in the sidebar and the file ID is in the URL, but a bit too much copypasting, especially when you need more than one mod. Sounds perfect for a simple QoL tweak to add!
