Depreciating GitActions

[jpolton]

Check GitActions are still all tip top.

Also noted the following:

This is to include the action across coast and coast-site repos ~ 14 workflows to look over

see if you can find the following action mentioned in COAsT #552

Time boxed to 1 day

We are not using save-state and set-output in our workflow commands. We are not using self-hosted runners or toolkits. So I guess this deprecating doesn't apply to the coastal package. @jpolton , can I close this issue?
