Description: This script processes JSON translation files for localization checks. It compares translation files in a branch with
a reference file to ensure consistency. The script performs two main checks:
1. Verifies that the number of translation keys in the translation files matches the reference file.
2. Ensures that all keys in the translation files are present in the reference file and vice versa.
The script also provides functionality to update the translation files to match the reference file by adding missing keys and
adjusting the format.
Usage:
python check_language_json.py --reference-file <path_to_reference_file> --branch <branch_name> [--actor <actor_name>] [--files <list_of_changed_files>]
