Rollup merge of #84340 - notriddle:patch-4, r=GuillaumeGomez

rustdoc: Show nag box on IE11 Rustdoc doesn't work on IE11. It's been broken for months, it isn't supported by the [tiered browser support list], it's even more severely broken on other Rust websites, and IE11 doesn't support the `<details>` tag that we want to use. In the interest of honesty, let's give an actual error message for anyone on IE11. [tiered browser support list]: https://github.com/rust-lang/rfcs/blob/master/text/1985-tiered-browser-support.md
