Palantir reformat landed on all supported branches

Hi all,
I took the slow day/week as an occasion to apply the Palantir reformat
on all supported branches of the geo-trio, as per GISP-228.

Everything is updated, hopefully that will make the code editing experience
a bit nicer. And oh, don’t forget to set the hard wrap limit in your editor at 120 columns now :rofl:

Thanks Andrea, that is great!

I have a PR here to update the developers guide for the new formatting: [GEOS-11659] Developer Guide formatting with Palantir by jodygarnett · Pull Request #8158 · geoserver/geoserver · GitHub

Thanks!
