Bug#1131238: ocaml-visitors: d/tests/control depends on ocaml-nox which has been removed

[Simon McVittie <smcv@debian.org>]

Source: ocaml-visitors
Version: 20251114-1
Severity: serious
Tags: forky sid
Justification: https://release.debian.org/testing/rc_policy.txt 6a
Usertags: ocaml-nox-rm
User: debian-ci@lists.debian.org
Usertags: regression

The ocaml-nox transitional package was removed by 
<https://bugs.debian.org/1125099>, but this source package still 
requires ocaml-nox for its autopkgtest. Please replace the dependency on 
ocaml-nox in debian/tests/control with a dependency on its replacement 
(presumably ocaml).

Thanks,
