Auto merge of #9945 - kraktus:uninlined_multiple_lines, r=llogiq

Re-enable `uninlined_format_args` on multiline `format!`

fix https://github.com/rust-lang/rust-clippy/issues/9719

There was an issue with the code suggestion which can be sometimes completely broken (fortunately when applied it's valid), so we do not show it.

changelog: [`uninlined_format_args`] re-enable for multiline format expression, but do not show the literal code suggestion in those cases
