For security reasons, fork PRs don't have access to secrets if we use `pull_request` in GH Actions CI spec, only if we use `pull_request_target`, which has its own security implications. See https://securitylab.github.com/research/github-actions-preventing-pwn-requests/ Codecov status reporting in CI requires a token, so for fork PRs to be able to do so we migrated to `pull_request_target` with the caveat that MRs have to be labelled and have the `run ci` label applied, which can only be done by someone with triage access to the repo. PRs originating from the original repo shouldn't require a label. This should give us a good compromise in terms of security.

Note⚠️
CI isn't running with these changes, because
pull_request_targetruns the workflow from the target branch, so only once this gets merged tomasterwill the workflow actually run as "expected".Description
Update
ci.ymlspecification to allow fork PRs CI to run codecov, but only when labelled with therun cilabel.
