Bug: Book build fails on Windows

[QingyaoLin]

When I cloned the project, I tried running mdbook build --open and it show:

> gh repo clone rust-lang/rustc-dev-guide
...
> cd rustc-dev-guide
> mdbook build --open
2025-01-10 23:07:31 [INFO] (mdbook::book): Book building has started

Book build failure!

Have you installed all the add-ons (check here what's needed)?
If so, I guess this line causes the issue (we use a shell script):

rustc-dev-guide/book.toml

Line 29 in aca4d07

command = "ci/linkcheck.sh"

If you want a copy, you can get it on the web (visit https://rustc-dev-guide.rust-lang.org/ and click the printer mark on top).

Also note that this repo is for developing rustc-dev-guide and it mainly happens on Unix-like OSes.
I'm happy to see a PR to work well on Windows, though!

I have installed all the add-ons.

This is kind of bad. When people who don't have a Unix-like system want to contribute, they won't be able to see the actual build results.

As I said in QingyaoLin:update-rustc-dev-guide-book, I don't know what happened in the middle and why the link was not detected as invalid.

Well, I haven't said that we don't welcome contributors outside of Unix 😓
Feel free to send a patch to fix that issue :)

I am not familiar with github CI and need other contributors to try to solve this problem. I will try my best to solve it.
