This commit removes 'mariadb' and 'mongodb' from the .gitignore file and adds '.data'. These changes ensure that project-specific data and generated files are properly ignored by the version control system.
This commit updates .gitignore and adds .idea/.gitignore to ignore certain directories and files. The tracked files that are now ignored include IDE-specific files, third-party libraries, environment variables, and database files, providing cleaner and more focused commits.
