Rollup merge of #99904 - GuillaumeGomez:cleanup-html-whitespace, r=notriddle

Cleanup html whitespace

I realized while looking at the raw HTML that we generated some unwanted white space characters. This PR cleans up the one coming directly from rustdoc. I'll check from `pulldown-cmark` for the remaining ones.

Some numbers now: the difference is small, it goes from `63009` to `62859`. But multiplied by the number of files, it becomes quite interesting overall.
