…ng it I missed this change due to the annotation not being there

For code hidden with `#` there must be a space after the `#`.

I had to do this myself recently and when I looked in this chapter it was "WIP" so I had to work it out myself. Might as well record it for the benefit of others.

`mdbook test` reports lots of errors. This commit fixes them, in various ways. - Add space after `#` on hidden lines. - Add `compile_fail` to all examples that are intended to not compile. - Add `text` to non-code blocks. - Add `ignore` to examples using `#![feature(...)]`, which requires nightly. Unfortunate, but I can't see a better way to handle these. - Add `edition2021` where necessary. - Add necessary hidden code.

`mdbook test` isn't run on CI! It should be. Plus some other CI improvements, based on the equivalent file at `github.com/nnethercote/perf-book/`: - Run actions on pull requests, to allow tests to run before merging. - Add some missing names for steps. - Update `actions/checkout` from v2 to v3.

this is also seen in the recent stabilization PR attempt: rust-lang/rust#122808 and rust playground confirms it.
