-Author: Ludy87
-Description: This script processes .properties 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 lines (including comments and empty lines) 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_properties.py --reference-file <path_to_reference_file> --branch <branch_name> [--actor <actor_name>] [--files <list_of_changed_files>]

-            ### Description of Changes
-
-            This Pull Request was automatically generated to synchronize updates to translation files and documentation. Below are the details of the changes made:
-
-            #### **1. Synchronization of Translation Files**
-            - Updated translation files (`messages_*.properties`) to reflect changes in the reference file `messages_en_GB.properties`.
-            - Ensured consistency and synchronization across all supported language files.
-            - Highlighted any missing or incomplete translations.
-
-            #### **2. Update README.md**
-            - Generated the translation progress table in `README.md`.
-            - Added a summary of the current translation status for all supported languages.
-            - Included up-to-date statistics on translation coverage.
-
-            #### **Why these changes are necessary**
-            - Keeps translation files aligned with the latest reference updates.
-            - Ensures the documentation reflects the current translation progress.
