Update existing deployment

[bradyclifford]

In cases where we want to set the deployment as pending, and then update it later to success. In most cases within the same GitHub deployment workflow.

But in cases where we deploy to a predeploy and do not automatically swap. Rather perform manually regression or enable a canary, we need to be able to update an existing deployment record later.

Provider a way to update said existing deployment with a completion status.

Perhaps this action can output the deployment ID.

And then take it as an input. If input exists, it replaces it instead of creating a new deployment.

However, I am not seeing a PUT or PATCH method to actually update an existing. This might not be possible.

This should do it:
