Remove reference to thirdparty untrusted github actions

[eolivelli]

• remove reference to untrusted styfle/cancel-workflow-action
• add workflow_dispach event in order to be able to trigger the execution manually from release branches

[eolivelli]

Please note that I pushed to the community repository in order to see the execution of the action per-branch and not only per-pr.

@sijie @Ghatage @jiazhai PTAL and merge if possible
the same fix is to be applied to Pulsar

[jiazhai]

Thanks for the work @eolivelli . There was already pr to fix this in Pulsar, also it is in-review status

[eolivelli]
