xleak: download ældre versioner

Release Notes
Added
- NetBSD installation via pkgin install xleak (thanks @0323pin! #40)
- Automated AUR, WinGet, and Scoop publishing via GitHub Actions
- Warn when formula cells are blank due to uncached xlsx values (NOTE: before table, suggests --formulas or re-saving in Excel/LibreOffice)
Changed
- Upgrade calamine 0.26 → 0.34 and dirs 5.0 → 6.0 for Debian packaging compatibility (thanks @nadzyah! #43)
- Nix flake version now read dynamically from Cargo.toml; homepage URL fixed
- Replaced prettytable-rs with comfy-table for non-interactive output, enabling correct multiline cell wrapping with --wrap (#44)
- Non-interactive table output: green bold headers, red errors, green formula-mode cells
Fixed
- CSV and text export wrote large numbers with thousands separators (e.g. "18,441,600,422" instead of 18441600422), making them unparseable as numbers (#34)
- AUR xleak-bin PKGBUILD: package() missing cd "$srcdir/..." caused install failures
- ? help keybinding not firing on macOS — macOS terminals omit SHIFT for symbol chars
- Formulas fixture: Formula column now shows expression text; Result holds the live formula
