This pull request refactors how pip is installed in virtual environments and improves the reliability of dependency installation. The main changes include moving the pip installation logic into a reusable function, updating the environment setup code to use this new function, and enhancing the pip_install function to automatically install pip if it's missing.

Refactoring and reliability improvements:

• Added a new install_pip function in utils.py to encapsulate the logic for installing pip using get-pip.py, including error handling for missing files or installation failures.
• Updated the environment setup in environments.py to use the new install_pip function instead of duplicating the installation logic.
• Improved the pip_install function to retry installation up to two times, automatically attempting to install pip if the error "No module named pip" is encountered. [1] [2]
• Updated imports in environments.py to bring in the new install_pip function.
