Update project configuration and enhance OpenTelemetry integration

- Modified `.gitignore` to include and manage `.devcontainer/signoz/data/*` while preserving `.keep` files.
- Updated `.prettierrc` to include the `@prettier/plugin-xml` plugin and configured XML formatting options.
- Added OpenTelemetry SDK and exporter gems to the `Gemfile` for enhanced monitoring capabilities.
- Removed `package-lock.json` as part of the transition to Yarn for dependency management.
- Enhanced `.devcontainer` configuration with new services for SigNoz, including ClickHouse and related configurations.
- Introduced new ClickHouse configuration files for user and cluster settings.
- Updated Nginx and OpenTelemetry collector configurations to support new logging and monitoring features.
- Improved user experience in the `UserSearchBar` component by updating the placeholder text.

These changes aim to improve project maintainability, monitoring capabilities, and user experience.
