Fix rare package registry typo

[wenxiaojie1]

Summary

• fix the rare_blaze_pacakge and rare_marble_gate_pacakge item registry typos
• rename the generated item model files to match the corrected registry ids
• update the Create packages item tag entries to use the corrected ids

Closes #93

Validation

• rg -n "pacakge" . returns no matches
• git diff --check

I also tried ./gradlew.bat compileJava --no-daemon, but the local build stopped during configuration with IBM_SEMERU, which appears to be a local Java/toolchain setup issue rather than a source-level failure from this change.
