Fix: Adjust dropdown menu item layout for better text fitting

- Updated the styling of `.DownloadsDropdownMenu__MenuItem` to improve text fitting and prevent text overlap.
- Changed `height` to `fit-content(25%)` to ensure the menu items dynamically adjust to content size.
- Added `flex-grow: 1` to allow the items to expand and occupy available space within the menu.
