feat(create): integrate version-aware pack.mcmeta generation into project creation

Added automatic rendering of pack.mcmeta from version data using Jinja2.
Introduced unified version metadata mapping for all Minecraft versions (1.19.2–1.21.10),
including pack_format, forge_gradle range, Java version, and other build parameters.
The create command now renders build.gradle, gradle.properties, MainMod.java, and pack.mcmeta
using version-specific templates from evermod-templates.
