Update deployment comment to reflect the removal of .../vk83/modules/access-models

[CodeGat]

Due to ACCESS-NRI/model-config-tests#41 (review) making the module path /g/data/vk83/modules/ instead of /g/data/vk83/modules/access-models, we need to update the deployment comment.

I changed the priority, because it seems like an easy fix and something that could really confuse users.

Note that I've also change the prerelease modules to be the same because @dougiesquire bullied me into it.
