Rollup merge of #137191 - ehuss:update-mdbook, r=jieyouxu

Update mdbook and move error_index_generator

This moves error_index_generator to the rustbook workspace so that it can share the dependency with mdbook. I had forgotten that error_index_generator is using mdbook.

This includes a corresponding update to mdbook which avoids a regression in error_index_generator.

Closes https://github.com/rust-lang/rust/issues/137052
