Rollup merge of #100959 - LuisCardosoOliveira:translation-rename-attr-warning, r=davidtwco

translations: rename warn_ to warning

## Description

This MR renames the the macro `warn_` to `warning`.

To give a little bit of context, as [explained](https://rust-lang.zulipchat.com/#narrow/stream/336883-i18n/topic/.23100717.20diag.20translation/near/295074146) by ``@davidtwco`` in the Zulip channel, `warn_`  was named like that because the keyword `warn` is a built-in attribute and at the time this macro was created the word `warning` was also
taken.

However, it is no longer the case and we can rename `warn_` to `warning`.
