[Fleet] Reenable flaky test and add longer timeout (#194843)

Closes #192999
## Summary

[Fleet] Reenable skipped flaky test. The
[beforeEach](#192999) conditions
in this test keep failing because they take longer than the 5s timeout
allowed for each test.

Here I'm adding an 8s timeout to attempt fixing it.
