Refactor release script for improved readability and robustness

[Adriel007]

This pull request implements several enhancements to the release script, aiming to enhance its readability, consistency, and robustness. Here are the key changes:

• Refactored the code to adhere to more consistent coding practices, including adding quotes where necessary to prevent word expansion and globbing issues.
• Updated the script to use set -eu instead of setting shell options in the header.
• Standardized variable names and error messages for better code comprehension.
• Replaced the usage of python3 for JSON parsing with jq, a more suitable tool for JSON manipulation.
• Checking for dependencies before using them in the script, ensuring necessary tools are installed.
• Improved code formatting and indentation for increased readability.

These changes are aimed at making the script easier to understand, maintain, and use, contributing to a more reliable and efficient release workflow.
