[DRE-maint] Bug#1094649: gem2deb: dh_ruby should not run the tests specified with DH_RUBY_IGNORE_TESTS

[Ananthu C V]

Package: gem2deb
Version: 2.2.5
Severity: wishlist

Dear Maintainer,

dh_ruby can currently take the environment variable DH_RUBY_IGNORE_TESTS
to skip tests, such as all tests or for specifically ruby3.1 etc. But what
it actually does is, instead of skipping the tests itself, it runs the
testsuite but ignores the errors.

This means that if a pacakge has in its d/rules files something like:
export DH_RUBY_IGNORE_TESTS = ruby3.1

It'd still run the tests for ruby3.1, but it would then ignore the test
failures if there is any.

When the variable is set, it should not be running those tests altogether,
or at the very least it would be better if the variable were to be renamed
to DH_RUBY_IGNORE_TEST_FAILURES if the current behaviour is to be retained,
although it does not really make sense to keep having that.
