ocaml-migrate-parsetree.2.2.0+stock fails to compile with ocaml.5.00.0+trunk

[shubhamkumar13]

OCaml.5.00.0+trunk doesn't work with the current ocaml-migrate-parsetree.2.2.0+stock and logs out the following error

#=== ERROR while compiling ocaml-migrate-parsetree.2.2.0+stock ================#

# Unknown OCaml version 5.00.0+dev0-2021-11-05

and since the current trunk's ast is not frozen it's best to wait for trunk to be frozen and then create a new ppxlib branch to work with OCaml.5.00.0+trunk in sandmark (since ocaml-migrate-parsetree is not needed for 5.0).

This would temporarily result in failure of a couple of irmin benchmarks

File "benchmarks/irmin/dune", line 4, characters 18-27:
	4 | 	(libraries irmin irmin.mem lwt lwt.unix))
	                      ^^^^^^^^^

	  dune external-lib-deps --missing --profile release --workspace ocaml-versions/.workspace.5.00.0+trunk @buildbench

Hence it seems best to currently track the benchmark failures in #261
and fix it when 5.0's AST is frozen.

#261 also removes the run_in_ci tag from run_config.json to remove the irmin benchmarks.

When this issue is resolved please add the run_in_ci in the tags field

OMP is no longer required for the trunk compatible ppxlib version: ppxlib.0.25.0~5.00preview
