NO SCAM - Both are correct
The one linked at the top menu "AddOns" -> "Addon Manager" should be the correct one.

The other is an older/same one, I guess both are correct as Minion belongs to the mmoui.com network afaik.
If you check the download links at
https://www.minion.gg/?download e.g. you can see it also links to:
https://cdn.mmoui.com/minion/v3/Minion3.0.5-32bit.exe
The download link at
https://minion.mmoui.com/?download is the same:
