correct template for `#[align]` attribute

Tracking issue: https://github.com/rust-lang/rust/issues/82232
related: https://github.com/rust-lang/rust/pull/142507

I didn't fully understand what `template!` did, clearly. An empty `#[align]` attribute was still rejected later, but without this change it does get suggested in certain cases.

I've also updated some outdated references to `#[repr(align)]` on functions.
