[new release] ocamlmig (5.3-20250429)

CHANGES:

- Switch to ocaml 5.3.
- Added experimental `ocamlmig replace` command, for a sed-like rewrites but working
  on ASTs instead of bytes.
- Reduce slightly dependency on ocamlformat, so this can be used on the compiler
  codebase
- Added `ocamlmig check` to typecheck the replacement in things like
  `val foo : int [@Migrate { repl = bar }]`
