Fix MTGJSON download: use .json files, remove gzip unpacking

- Changed REQUIRED_FILES to REQUIRED_JSON_FILES and REQUIRED_ZIP_FILES
- AllSetFiles.zip kept as zip (only available compressed on MTGJSON)
- All other files downloaded as .json (no compression)
- Removed gzip import and unpacking logic for .gz files
- Updated EXPECTED_MIN_SIZES to reflect actual .json file sizes
- Removed validation for non-existent files
