feat: enhance Java version management for Minecraft versions

Added functionality to determine and validate the required Java version for Minecraft versions, including checks for compatibility with older versions. Implemented event emissions for version installation and deletion, and updated the UI to reflect Java version requirements and installation status. Improved version metadata handling and added support for deleting versions.
