feat: Backup Patch sources

[J4CKED]

Feature description

A general copy of the settings does not save added patch sources. Please include them in the backup.

Motivation

I know that backup programs can be used, but since there is an option to export settings, it would be nice to add a function to save added patch sources.

Acknowledgements

This is not a universal manager for other patch sources ).
There are other managers for this, including URV-Universal ReVanced Manager, where all this is implemented, and not only that.
