Newest ocaml grammar incompatible with current ocaml file

[mkatychev]

Describe the bug
Though the newest ocaml grammar should be more performant than the existing one:

$ cat ocaml/grammars/ocaml/src/parser.c | rg "#define.*STATE"
#define STATE_COUNT 8273
#define LARGE_STATE_COUNT 1733

The current input & expected ocaml.ml produces (ERROR) nodes when using latest gramamr

To Reproduce
Modifying the rev below to 3ef7c00b29e41e3a0c1d18e82ea37c64d72b93fc should produce errors

topiary/topiary-config/languages.ncl

Lines 54 to 62 in f4b67a0

	ocaml = {
	extensions = ["ml"],
	grammar.source.git = {
	git = "https://github.com/tree-sitter/tree-sitter-ocaml.git",
	rev = "a45fda5fe73cda92f2593d16340b3f6bd46674b8",
	subdir = "grammars/ocaml",
	nixHash = "sha256-u8R3JvjaOrW6kCX1hNTGMl86HnKAoopSMvHr8Sj0i04=",
	},
	},

Expected behavior
Though node names are not expected to be backwards compatible, documents to parse should

Environment

• OS name + version: macOS
• Version of the code: latest main

Additional context

This is especially relevant because current ocaml grammar takes almost 9 minutes to run by itself, this is a huge drain on CI and local wait times.
