Install melange.5.0.0-52 in CI (#882)

* check only the visible hover type, not the entire tree

* check only the visible hover type, not the entire tree in issue-429

* force melange.5.0.0-52 in devsetup

* check only the visible hover type, not the entire tree in uppercase

* check only the visible hover type, not the entire tree in uppercase, annotate errors

* annotate regressions on keys.t

* remove DUNE_CACHE_ROOT from blackbox-tests

* make sure ppxlib.0.33.0 is used in reason-react-ppx for dev-setup

* change with-dev-setup into with-test for melange

* since ppxlib#530 -dparsetree doesn't print locations
