make tests trigger for external contributors

[motatoes]

In most of our tests we listen for:

  pull_request:
    types: [opened, reopened]

It seems to not trigger for external cotributors. We should replace it with:

  pull_request:

because that seems to work better

Will likely want to have something like:

    if: github.event.pull_request.head.repo.full_name == github.repository

or

    if: github.repository_owner == 'diggerhq'

in the job definition header as well to avoid forks running tasks in the source repo etc..that could expose things that might not want to be exposed.

Yeah so true, that will be needed. I think the only one that exposes secrets is the e2e tests, rest don't contain sensitive data :)
