Auto merge of #84552 - GuillaumeGomez:open-impl-blocks-by-default, r=jsha

Open impl blocks by default

Fixes #84558.
Part of #84422.

As you can see on https://doc.rust-lang.org/nightly/nightly-rustc/rustc_middle/ty/context/struct.TyCtxt.html, impl blocks are currently not open by default whereas they should.

I also realized that a test was outdated so I removed it and opened #84550 because it seems like the rustdoc-gui test suite isn't run on CI...
