🚀 Feature request: Donation options

### 🔖 Describe the solution you'd like

Bring back the Donations page. _This can only be done for Windows and GithubPagesWindows (and maybe FDroid type) platformTypes since it is against the App Stores policies to have any payment method that they do not own_.

Additional tasks:
- [ ] Centralize donation links
- [ ] Add LibrePay option
