e2e conversion test intermittently times out when cleaning up resources

[A clear and concise description of what the bug is.]

The test [It] [unmanaged] [Cluster API Framework] Clusterctl Upgrade Spec [from latest v1beta1 release to v1beta2] Should create a management cluster and then upgrade all the providers often fails due to timeout in CI.

The upgrade test itself seems to pass, but teardown fails.

The output looks like something:

The above output may be a red herring, however - there's also this log line that indicates that we're not gett the collection logs from the cluster made to do the upgrade test, while the cluster being torn down in the pasted section is functional-gpu-cluster-wqgqck/functional-gpu-cluster-44q1nj.

What did you expect to happen:

Test resources are cleaned up without timeout.

Anything else you would like to add:
