infra: Allow webui tests for external contributors

Currently, we need to manually execute web UI tests for external
contributors on each Anaconda PR. This is security precaution to avoid
malicious code to be executed on Cockpit runners.

However, our project is configured that we need to manually allow all
the workflows by pressing a button for every tests run for external
contributors. The webui case is making the same requirement twice for
this specific test.

To avoid unnecessary burden with not giving us much benefit, let's allow
external contributors for every run automatically. Press of the GitHub
button on PR should be good enough confirmation that there is no
malicious code.
