Library publishing workflow doesn't like LIBAPI changes

[jnsgruk]

Bug Description

Recently the snap library was bumped to v2 in canonical/operator-libs-linux#92.

The CI didn't seem to catch that, which you can see here

To Reproduce

Update a library LIBAPI version, moving the file into the new version

Environment

operator-libs-linux repo

Relevant log output

/usr/bin/sudo snap install charmcraft --classic --channel latest/stable
charmcraft 2.3.0 from Canonical** installed
/snap/bin/charmcraft list-lib operator-libs-linux --format=json
