fix: improve accessibility for file-tree components

- Convert clickable div to semantic button in artifacts-section
- Add aria-hidden to decorative icons
- Add aria-label to rename inputs and hidden file inputs
- Add i18n keys for artifacts section and rename labels
- Support ignore file extensions (.gitignore, etc.)
