Update to Ruby 3.3.0?

can, shall we update to ruby 3.3.0?

Latest is greatest! IMO we should update as soon as Rails supports it.

Rails support should not be an issue. Last time we discussed this, I was a bit hesitant, bevause the .0 versions sometimes had issues in the past.

But it has been two months, I know of huge companies running 3.3 in production, and nothing has come up thus far that I am aware of. So let us do it.

okay, will prepare a PR for this.
