Make Actions tasks/jobs timeouts configurable by the user (#27400) (#27402)

Backport #27400 by @fantognazza

With this PR we added the possibility to configure the Actions timeouts
values for killing tasks/jobs.
Particularly this enhancement is closely related to the `act_runner`
configuration reported below:
```
# The timeout for a job to be finished.
# Please note that the Gitea instance also has a timeout (3h by default) for the job.
# So the job could be stopped by the Gitea instance if it's timeout is shorter than this.
timeout: 3h
```

---

Setting the corresponding key in the INI configuration file, it is
possible to let jobs run for more than 3 hours.

 `DEFAULT_ACTIONS_URL` indicates where the Gitea Actions runners should find the actions with relative path.
 For example, `uses: actions/checkout@v3` means `https://github.com/actions/checkout@v3` since the value of `DEFAULT_ACTIONS_URL` is `github`.
