Description

• Allows running ts-ci workflow on pull requests coming from forks.
• Replaces trigger for pre-release workflow to be pull_request. As per following recommendation, the pre-release should not be needing write permissions as its a dry run:

Workflows triggered via pull_request_target have write permission to the target repository. They also have access to target repository secrets. The same is true for workflows triggered on pull_request from a branch in the same repository, but not from external forks. The reasoning behind the latter is that it is safe to share the repository secrets if the user creating the PR has write permission to the target repository already.
