Fix kubectl apply timeout with slow network

Cloning https://github.com/stolostron/multicloud-operators-foundation.git
during `kubectl apply --kustomize` can fail with a timeout when using
slow network:

    $ kubectl apply -k test/addons/ocm-controller --context hub error: accumulating resources:
    accumulation err='accumulating resources from
    'https://github.com/stolostron/multicloud-operators-foundation.git/deploy/foundation/hub/overlays/ocm-controller?ref=main':
    URL is a git repository': hit 27s timeout running '/usr/bin/git fetch --depth=1
    https://github.com/stolostron/multicloud-operators-foundation.git main'

Turns out that the way to increase the timeout is to add a `timeout`
query parameter[1]. Use 300 seconds to avoid random failures when using
poor network.
