refactor: ♻️ do not generate prisma on "postinstall"

This commit updates the 'prepare' script on the package.json file, removing the redundant 'db:generate' command. This change simplifies the script execution and avoids unnecessary database generation on every install. Furthermore, a new .gitignore file was added to the infrastructure folder in order to ignore all files within .terraform directory, keeping the repository cleaner and preventing unwanted files from being tracked.
