Allow support for explicit lwjgl versions

[scotus-1]

This allows for an explicitly defined version of LWJGL in the [versions] section of pack.toml. My reasoning for this is I distributed my modpack through multimc and shipped it with LWJGL version 3.3.3, in later updates of Sodium, this crashes.

low key this took me 6 hours to add two lines because i had to find the cmd line option to disable packwiz updating to test my local build but this works
