[chore]: Pipelines for CI/CD

[lukepistrol]

Currently all our actions get triggered by on-push or on-pull-request events and run in parallel. The problem with that is, that for example after pushing to the main branch, if the tests were to fail, the pre-release would be deployed anyway.

To mitigate this issue I implemented pipelines for both on-push events on main as well as on-pull-request events.

• on-push: SwiftLint -> Tests -> Deploy Pre-Release
• on-pull-request: SwiftLint -> Tests

Now if any job fails, no succeeding job will be run and the whole pipeline fails. Since we would not want to deploy a pre-release with a potential error.
