Fixing #168 once again uncovered the charmbracelet/bubbletea#964 bug

Fixing #168 with #170 we have, once again, uncovered the charmbracelet/bubbletea#964 bug.

See the error, here: https://prow.knative.dev/view/gs/knative-prow/pr-logs/pull/knative-extensions_kn-plugin-event/339/integration-tests_kn-plugin-event_main/1773009898955608064#1:build-log.txt%3A644

To confirm that, you can checkout the knative-extensions/kn-plugin-event#339, and run (passing a file as stdin):

$ ./mage clean build < go.mod

It looks like the /dev/stdin doesn't support the epoll thing.
