Rebuild SolitaireCG with SdkVersion = 23

Hi all.

I’m quite addicted to SolitaireCG (SolitaireCG | F-Droid - Free and Open Source Android App Repository)
Unfortunately it can not be installed on a Samsung Galaxy Tab S9 because it refers to SdkVersion 4 and the Tab S9 insists on SdkVersion 23.
Can somebody please change the SdkVersions in app/build.gradle and rebuild it? I will then test it and report back.

Pardon for not trying to do it myself, but I’m only a desktop developer and have no experiences with Android development.

Regards, Georg
