Subject: [PATCH 1/2] Add post-install commands to install.js

Added functionality to handle and run post-install commands after the packages installation. This includes the extraction of 'postInstall' from the config data, running post-install commands concurrently after plugins and themes installation, and a new method 'runPostInstallCommands' for executing these commands. This allows users to perform necessary actions automatically after the package installation process.

Subject: [PATCH 2/2] Add WP-CLI availability check before post-install
 commands

Added a function `isWPCLIAvailable` in `utils.js` to check if WP-CLI (WordPress Command Line Interface) is available on the system. This function is then used in `install.js` before running post-install commands. This prevents errors and provides a better user experience if WP-CLI is not installed and a post-install command depends on it.
