[danehans]

The API docs generators should be called by the release target to ensure the API docs are up-to-date when releasing.

I'm not sure the fix is as simple as described due to how our site works atm: #1431 (comment)

I agree with ^. Instead, the release issue template should be updated to include a step of running the API docs generators against main instead of the release branch.
