https://doc.rust-lang.org/error-index.html is not getting updated

[kpreid]

The text at https://doc.rust-lang.org/error-index.html is stale compared to what appears to be its source material, https://github.com/rust-lang/rust/tree/master/compiler/rustc_error_codes/src/error_codes.

For example, the section for E0038 uses the deprecated dynless syntax Box<Trait>, but the markdown file in Git does not and has been substantially revised.

I found that the file is generated by src/tools/error_index_generator into build/<target>/doc/error-index.html, but I don't know how that file should get deployed to doc.rust-lang.org.

I believe this is just a case of needing to wait until the relevant PR hits stable -- the top-level files on doc.rust-lang.org are updated on each stable release. In this case, #91387 needs to hit stable which will happen later this week. Closing as not-actually-a-bug.
