Links in tutorials point to version-non-specific crates

[echeran]

In data-management.md, there is Markdown containing a link, such as

You can learn more about datagen, including the Rust API which we have not used in this tutorial, by reading [the docs](https://docs.rs/icu_datagen/latest/).ou can learn more about datagen, including the Rust API which we have not used in this tutorial, by reading [the docs](https://docs.rs/icu_datagen/latest/).

This may occur throughout the entire tutorials content.

However, as we've discussed, tutorials are inherently versioned content. Therefore, all such links should be versioned.

This probably needs to be fixed by a script during copying to the website repo, as we can't update all the links everytime we bump a version number.

So long as the repo links were valid at the time the tag was created, it seems harmless for the md-to-astro script to replace https://docs.rs/<XYZ>/latest/ with https://docs.rs/<XYZ>/<VERSION>/
