Increase timeout for Operator Hub tests (#4248)

This increased timeout makes sure that `odo catalog list services` being
executed in `JustBeforeEach` gets enough time to check for existence of
two Operators that we're installing in CI to perform our checks.

We need to increase this timeout because it's taking a long time for
`odo catalog list services` to find "successfully installed" Operators
in the newly created namespace even if these Operators are installed at
cluster level, i.e., in the `openshift-operators` namespace.

The increase in the time taken by odo to find this info is mainly
attributed to #4202. I am observing
that even `kubectl get csv` is taking more than usual time to list the
Operators or report their phase as "Succeeded" but there's not enough
data to back that up. So, in the interim, this seems like best way to
make sure that CI doesn't keep failing on `JustBeforeEach`.
