ci: handle gradle action deprecations

[ewanharris]

Description

Noticed a warning about this on the release job so figured we should switch over, it's functionally identical just renamed.

Also changes the publish step to the new way of setting up gradle and then calling the tasks as arguments is now deprecated too
