The deployments API action does not work with external contributors

[lupino3]

In PR #616, the Deployments API Github Action fails because the initiator of the action does not have write permissions on the repo:

There are lots of similar issues
actions/first-interaction#10
actions/create-release#103

We should look into making that step of the actions optional or find a workaround for the authentication.

There are ways to delegate permissions, but I'm not fully comfortable with delegating tokens to external repos.

We should see if we can remove the usage of deployments API and fall back to just deploying the code, maybe just sending a message on the thread with the URL.
