Feat: Add support for JSONL file translation

[fadkeabhi]

Overview

This PR adds support for translating JSONL (JSON Lines) files as discussed in this issue #50

Implementation Details

• Added detection for JSONL file format based on file extension

• Implemented conversion of JSONL to JSON array:

  • Each line from the input JSONL file is parsed as a separate JSON object
  • All objects are collected into a single array for processing

• Added reverse conversion for output:

  • The translated JSON array is split into individual objects
  • Each object is written as a separate line in JSONL format

PS:

• skip already translated keys feature is not implemented for jsonl files yet.

Let me know if any changes or additional information is needed!
