All its warnings are extracted into the bundle, but they are still poorly
adapted for translation. Each of them in constructed from two separate
messages, a common prefix and an individual feature description, with negation
of the main verb being split. Only the first message can vary depending on
the affected versions number, but both parts of the verb need to agree in many
languages other than English. It's not clear how to address it without
overhauling inspection internals, thus it will be revised later.
I also slightly updated the warnings format. Namely, put "version" in plural,
if a warning applies to multiple Python versions, and removed trailing periods
from single-sentence messages.
