ppxlib's Transition

We are following a multi-step plan to keep the PPX ecosystem up-to-date without coordinating with the compiler devs. You can find that plan's contents and its current status on our wiki page about it.

Furthermore, there are some discuss.ocaml.org posts about the transition reflecting the situation at the time they were written:

• In October 2023, @pitag-ha gave a historic summary when giving space for feedback and objections to the community wrt the deprecation of ocaml-migrate-parsetree
• In July 2021, @pitag-ha summarized the transition in detail and give an update on its state
• In February 2021, @NathanReb announced the release of the ppxlib version containing the AST bump to 4.12 and explained our workflow of sending patch PRs to PPXs we'd break
• In August 2020, @jeremiedimino announced the upcoming OMP2 release and pointed out what the next steps would be
• In June 2020, @jeremiedimino explained how OMP2 would look like and what the OMP major release would imply
