Rollup merge of rust-lang#53082 - felixrabe:fix-doc-link-again, r=GuillaumeGomez
Fix doc link (again) Similar to rust-lang#52404. The link for comparison: - https://doc.rust-lang.org/book/second-edition/ch19-04-advanced-types.html#dynamically-sized-types-and-sized (broken) - https://doc.rust-lang.org/book/second-edition/ch19-04-advanced-types.html#dynamically-sized-types-and-the-sized-trait (correct, stable 2nd ed) - https://doc.rust-lang.org/nightly/book/second-edition/ch19-04-advanced-types.html#dynamically-sized-types-and-the-sized-trait (correct, nightly 2nd ed) - https://doc.rust-lang.org/nightly/book/2018-edition/ch19-04-advanced-types.html#dynamically-sized-types-and-the-sized-trait (correct, nightly 2018 ed) This commit is the result of (first) searching via ripgrep (0.8.1 -SIMD -AVX): rg -l dynamically-sized-types-and-sized and then replacing all relevant occurrences via: find src/{libcore,test/ui} -type f -print0 | xargs -0 sed -i.bak \ s/dynamically-sized-types-and-sized/dynamically-sized-types-and-the-sized-trait/g find src/{libcore,test/ui} -type f -name '*.bak' -print0 | xargs -0 rm (Note: Tested on on macOS 10.13 (BSD). `sed -i.bak` should work on Linux (GNU sed) as well, but not tested.)
