Automatically update URL to point to the selected version for easy sharing

[gigaherz]

When sharing versions with people, it would be extremely convenient to be able to give them a link with the version automatically selected.

The page already supports syntax like

https://projects.neoforged.net/neoforged/neoforge?minecraft_version=21.1&neo_version=21.1.8

so this request is just to update the URL to include those additional get params when the version changes.

Bonus points: We could shorten the url to https://projects.neoforged.net/neoforged/neoforge/1.21.1/21.1.8 using path elements instead of query

Example of this concept in action: https://adoptium.net/temurin/releases/?arch=riscv64&package=jre -- the page automatically updates the url to match the selected filters.
