[FEATURE REQUEST] Importing cross platform applications using repology

### Please confirm these before moving forward.

- [x] I have searched for my feature proposal and have not found a work-in-progress/duplicate/resolved/discarded issue.
- [x] This proposal is a completely new feature. If you want to suggest an improvement or an enhancement, please use [this template](https://github.com/Devolutions/UniGetUI/issues/new?labels=enhancement&projects=&template=enhancement-improvement.yml&title=%5BENHANCEMENT%5D+%28Enter+your+description+here%29).

### Describe the new feature

For example, use repology's information on chocolately/scoop apps on windows to import same application corresponding to linux on supported package manager.

Unfortunately repology has paused/stopped indexing winget packages, see: repology/repology-updater/issues/1392 due to some issue with parsing winget data. Possibly, devs here can either try maintaining their own version to help this similar to icons and screenshots using repology's old parsers, or to help the winget/repology projects themselves.

### Describe how this new feature could help users

Useful while migrating OS. I used UnigetUI's backup tool and manually installed apps I had on windows, this would save that trouble.

Particularly helpful for end of windows 10 users due to its extended EOL (14 Oct 2026) and TPM2.0 requirements, see [endof10.org](https://endof10.org/) and for simple tools/guides helping users migrate linux, see also [operese](https://www.youtube.com/watch?v=4YUkD5oslmc) tool that was popular for being a simple tool trying to help that.
