`hugo server` fails local build with many `REF_NOT_FOUND`

### What's Wrong?

Running `hugo server` locally reports a number of issues for `REF_NOT_FOUND`. This was discovered during the v2.4 release process https://github.com/crossplane/docs/issues/1135, but it appears to be reproducible on main before the v2.4 release also.

Errors:
```

They all seem to be related to links with `/latest/` either to or from the CLI docs.
