New actions for new beta process

[adcreare]

Closes #43
Closes #44
Closes #47

I've tried to keep the actions seperate and self contained, not sure if that's a good approach, open to ideas if we should consolidate some operations (like the github operations) that are used by a bunch of actions.

Could be in another PR, but also added #46 which I think we need as well.

Ok I think this PR is probably grown large enough.. its what hash is using at the moment.
When we're happy with this I'll update the PR in hash two switch this over to main.
