Use correct Hermit links in The `rustc` Book

As is, this documentation links to the old Hermit organization, `hermitcore`, which isn't used anymore.

I've updated the links to point to the new organization. This PR also changes the incorrect "rusty loader" link to point to the new `hermit-rs-template` repo.

(fixes #124722)
