sembr some rustdoc files and improve them a bit

This fixes some code block tags that aren't using the correct language for rust.

This was incorrectly interpreting the value as an HTML tag. This wraps it in an code span to avoid that.

arm-android: 5829.0s -> 6494.4s (+11.4%)

How to interpret the job duration changes?

Job durations can vary a lot, based on the actual runner instance
that executed the job, system noise, invalidated caches, etc. The table above is provided
mostly for t-infra members, for simpler debugging of potential CI slow-downs.
