Auto merge of rust-lang#127931 - GuillaumeGomez:switch-to-rinja, r=<try>

Replace askama with rinja Another askama maintainer and myself forked it and named the fork rinja. The whole difference is explained in this [blog post](https://blog.guillaume-gomez.fr/articles/2024-07-16+docs.rs+switching+jinja+template+framework+from+tera+to+rinja) (not publicly released yet, waiting for docs.rs to deploy the new version using it before). But in short, rinja got a lot of improvements and compiles faster, so I think it's definitely worth it to use it in rustdoc as well. r? `@notriddle`

 We want our templates to be readable, so we use indentation and newlines
 liberally. We indent by four spaces after opening an HTML tag _or_ a Jinja
 tag. In most cases an HTML tag should be followed by a newline, but if the
 tag has simple contents and fits with its close tag on a single line, the
 contents don't necessarily need a new line.
