The invoke task update-openapijson is incomplete

[CasperWA]

The invoke task update-openapijson only copies over the local openapi JSON files, but does not update them before-hand, i.e., if you are developing and switching between branches, you will mix up your openapi JSON files from different branches (since the local openapi JSON files are not tracked via git).

This can be remedied quite simply by updating the local openapi JSON files prior to copying them.

Note: I believe this is what has caused the failling jsondiff pre-commit as well, since this may not always run locally, I guess?
