10.1.0 - by Zoriot:

         - Makes Self Updater work fine with Ptero Setups
         - Disable Java update on Ptero (force-enable option added if needed)
         - New fallback download rule: This rule permits files with a text/plain content type to pass validation, provided that the file name ends with a .jar extension.
         - Support for Velocity and Bungeecord plugin updates via the Modrinth API by replacing a hardcoded loader approach with a dynamic, server-software-aware system.
