The STAC Node Validator fails the deploy step because the URI of ML-AOI schema cannot be found, but I want to validate everything works with mocked schema locations before releasing them. We have a chicken-egg situation here.
I would like to know your preferred approach regarding the CI for STAC extensions and resolving those missing refs issues.

That's not the case. The validator can handle this case. You need to specify the correct version numbers in package.json (search for 1.0.0 occurances and replace with 0.1.0). Generally, I'd recommend to search (and replace) the whole repo for "template" and "1.0.0" and replace it with the corresponding values that apply for this repo. Afterwards delete release and tag and release again with the updated files.

I see. And once I bump the versions with the new minor release, I simply need to update the package.json with the relevant numbers as well?

yes
