Configure 'Organize Imports' to avoid unecessary commit noise.

I noticed that some of my recent PR's changed wildcard imports to actual imports, e.g.,

import static org.junit.jupiter.api.Assertions.*;
// vs
import static org.junit.jupiter.api.Assertions.assertEquals;
import static org.junit.jupiter.api.Assertions.assertTrue;

I think this comes from the fact, that the LSP4E projects don't have project specific settings for handling imports, e.g.:

Thus, the IDE falls back to the workspace settings, which are probably different for every committer.
To avoid unnecessary commit noise we should probably configure these settings.

Personally, I'm leaning slightly toward named imports, but in the end, I don't really care, as long as we all use the same settings.
