Add a dune upper bound for tezt 3.1.0-4.2.0 with-test

[jmid]

On a number of PRs I've observed tezt failures to run with-test, e.g., on #28437
https://opam.ci.ocaml.org/github/ocaml/opam-repository/commit/c56e58d25e43ce7dd35f9942ad32b42e22d608c9

tezt.3.1.0 (failed: The compilation of tezt.3.1.0 failed at "dune runtest -p tezt -j 255".)
tezt.3.1.1 (failed: The compilation of tezt.3.1.1 failed at "dune runtest -p tezt -j 255".)
tezt.4.0.0 (failed: The compilation of tezt.4.0.0 failed at "dune runtest -p tezt -j 255".)
tezt.4.1.0 (failed: The compilation of tezt.4.1.0 failed at "dune runtest -p tezt -j 255".)
tezt.4.2.0 (failed: The compilation of tezt.4.2.0 failed at "dune runtest -p tezt -j 71".)

and now again today on #28544
https://opam.ci.ocaml.org/github/ocaml/opam-repository/commit/8165ebc987d9de35b2fdba552fd80e37f5bd842d

The issue turns out to be caused by dune.3.19.0 changing the observed value of Sys.argv.(0) - which happens to be printed in the test suite (in cram tests) of tezt 3.1.0-4.2.0 ocaml/dune#11881

I've confirmed locally that opam install tezt --with-test installs cleanly with dune.3.18.2 and below.
According to the above issue the change of behaviour should be rolled back with dune.3.19.1, however
locally with ocaml.4.14.2, dune.3.19.1, and tezt.4.2.0 I still observe test failures:

I've therefore gone with a hard < 3.19.0 bound for all 5 tezt version where we've observed the failure.
Note: this is not a hard bound - only a bound for where we run the tezt testsuite.

Adding these bounds reveal additional run-test failures that I need to look into.
I've therefore added the do not merge label.
