bug: Entering an invalid patches source url shows a confusing error message

[LisoUseInAIKyrios]

Bug description

Bug description

1. Add any invalid patch source such as https://github.com/non_existent_user!!11/huh or http://google.com/i_dont_understand_patches
2. Manager shows an error toast with an un-intuitive error message
3. Patch source in Manager shows an error icon

This issue is similar but not the same issue as the lack of backwards compatible reported in #2788

Manager should show a more informative error message and it should not add the broken url as a patch source.
