Bioportal mappings fail with `AttributeError`

Running the `mappings` command with `bioportal` results in an `AttributeError`.
This includes the examples in the docs: https://incatools.github.io/ontology-access-kit/examples/Command-Line-Examples.html#BioPortal

On a fresh install:
```bash
$ pipx install oaklib
installed package oaklib 0.6.23, installed using Python 3.12.3
These apps are now globally available
- boomerang
- runoak
- vskit
done! ✨ 🌟 ✨
```
```
$ runoak -vvv -i bioportal: mappings CTENO:0000018 -O sssom

The semsql version does not produce this error (though there are no mappings in this case):

Start by reproducing the documented `runoak -i bioportal: mappings CTENO:0000018 -O sssom` command under Python 3.12 and trace the `collections.Iterable` error through the BioPortal mappings path. Done means the command completes without this AttributeError and the BioPortal example in the linked documentation works.
