This continuation of work at rust-lang#98861

It's misleading. The main heading sometimes isn't an fully qualified name at all.

It's also redundant. It's always a child of `div.main-heading`, so just use that.

This swaps things around so that the class that gets used more often has
the shorter name.

reword Option::as_ref and Option::map examples

The description for the examples of `Option::as_ref` and `Option::map` imply that the example is only doing type conversion, when it is actually finding the length of a string.

Changes the wording to imply that some operation is being run on the value contained in the `Option`

closes rust-lang#104476

mv binary_heap.rs binary_heap/mod.rs

I confess this request is somewhat selfish, as it's made in order to ease synchronisation with my [copse](https://crates.io/crates/copse) crate (see eggyal/copse#6 for explanation). I wholly understand that such grounds may be insufficient to justify merging this request—but no harm in asking, right?

Remove duplicate sha-1 dependency

[`sha-1`](https://crates.io/crates/sha-1) is more or less a duplicate of [`sha1`](https://crates.io/crates/sha1). The `sha-1` is deprecated and no longer updated. This updates the dependencies to use the new name.

Some other dependencies that got updated as a consequence:
* The updated pest dependencies are currently only used by mdbook, and shouldn't have any issues.
* ucd-trie 0.1.3 to 0.1.5: No changelog, but looks like some tables were updated for new unicode versions: https://github.com/BurntSushi/ucd-generate/commits/master/ucd-trie. This is only used by pest (and thus mdbook).
* thiserror 1.33 to 1.38: Nothing significant in the notes at https://github.com/dtolnay/thiserror/releases.

Stop having unused lifetimes on some `impl`s

See <https://doc.rust-lang.org/nightly/std/cmp/trait.PartialOrd.html#impl-PartialOrd%3COsStr%3E-for-PathBuf>, where these lifetimes show up even though they're not needed:

With this PR, the unneeded lifetimes are no longer there:

Update `rental` hack to work with remapped paths.

This PR simply switches to an already-existing helper instead of hard-coding a specific enum variant. The new revision of the test fails without the other changes in this PR.

Context: I'm exploring running UI tests with remapped paths by default in rust-lang#105924 and the rental test was one of the ones that failed.

This may also be useful in the context of rust-lang/rfcs#3127 ("New rustc and Cargo options to allow path sanitisation by default").

rustdoc: remove unnecessary DOM class `h1.fqn`

It's misleading. The main heading sometimes isn't an fully qualified name at all.

It's also redundant. It's always a child of `div.main-heading`, so just use that.
