GopherJS 1.19.0 beta1 for Go 1.19.13

Hi Gophers!

We know it's a bit overdue, but at last we are ready to present you a new GopherJS release updated for Go 1.19. Initially we intended to finish generics support before picking up 1.19, but thanks to @grantnelson-wf we were able to work on both in parallel. Please note that generics support is still not merged, but it is getting very close, honestly! 😅 Like with 1.18, we will release 1.19 as a beta release until generics are ready for general use.
