APPLE_STRINGS format adds unwanted blank lines between keys

[exponentChoi]

Version: 2.13.0

Problem:
When using tolgee pull with --format APPLE_STRINGS, the output file contains unwanted blank lines between each key-value pair.

Expected:

"key1" = "value1";
"key2" = "value2";
"key3" = "value3";

Actual:

"key1" = "value1";

"key2" = "value2";

"key3" = "value3";

Impact:

• File size doubles unnecessarily
• Reduced readability
• Inconsistent with standard Apple .strings format
