Starting with Java 20, instantiating URLs via new URL is deprecated in favor of URI#toURL().

While the project's codebase targets Java 17, we can address backwards-compatible deprecations still.

The file of concern is the following: https://github.com/search?q=repo%3AIntellectualSites%2Ffastasyncvoxelsniper%20%22new%20URL%22&type=code

More information about the deprecation can be found in the javadocs and constructor deprecation.
