chore: improve editor configuration, pre-commit hooks, and VSCode settings (#3780)

# Description of Changes

- Added `charset = utf-8` and defined `indent_size = 2` for `*.css`,
`*.json`, `*.jsonc`, and `*.yml` in `.editorconfig` to ensure consistent
formatting across file types.
- Improved labeler rules in `.github/labeler-config-srvaroa.yml` by
expanding path coverage for labeling Java and CI-related files.
- Upgraded pre-commit hooks:  
  - `ruff` from `v0.11.11` to `v0.12.0`  
  - `gitleaks` from `v8.26.0` to `v8.27.2`  
- Updated `codespell` args to ignore new terms like `thirdParty`,
`tabEl`, `tabEls`.
- Enhanced `.vscode/settings.json` and `extensions.json`:  
- Added formatting rules for `json`, `jsonc`, `markdown`, `python`, and
`gradle` files.
  - Included additional extensions for Markdown and Gradle.  
  - Applied detailed HTML formatting preferences.
