Update dependencies and modify .gitignore

This commit updates various dependencies in the `yarn.lock` file to newer versions to maintain compatibility and security. It also adds `gradle.properties` to the `.gitignore` file, preventing it from being tracked by Git. The updates aim to enhance stability and maintainability of the codebase.
