fix(ui): correct invalid tailwind line-height class typo in features.tsx

### Bug Description
In `src/pages/features.tsx` (line 54), there is a typo in the Tailwind CSS line-height class for the Podman Desktop link.

The class is written as `leading-releaxed`. Because this is an invalid class name, Tailwind CSS ignores it entirely, resulting in broken/default line height rendering for that element.

### Proposed Solution
- Correct the typo from `leading-releaxed` to the valid Tailwind class `leading-relaxed`.
- I am happy to submit a PR to fix this!

Open src/pages/features.tsx and inspect line 54, where the Podman Desktop link uses the invalid leading-releaxed class. Correct the typo to leading-relaxed. The issue is done when that element uses the valid Tailwind line-height class.
