Conflict between `unit-test-is-not-verb` and `bad-test-name` lints over `can-` prefix in positive test names

Two lints in the same jar ask for opposite things about a positive test name. bad-test-name in src/main/resources/org/eolang/lints/tests/bad-test-name.xsl requires it to match ^(can|accepts)-, and LtTestNotVerb hands the same title to Vocabulary.isVerb, which tags it with OpenNLP and accepts it only when the first word is VBZ. can is a modal, tagged MD, so every name the first lint allows in its can- form the second one rejects.

The collision only surfaced in 0.4.9, since MonoLints in 0.4.8 held no reference to LtTestNotVerb and the check never ran. In objectionary/eo it now fires 1972 times against eo-runtime, which is every positive test in the module, and the only spelling that satisfies both lints is accepts-, which reads wrong for most of them: accepts-negate-false is not what the test says.

Either unit-test-is-not-verb should accept the modal that its sibling lint mandates, or the two should agree on one prefix set.
