[EDR Workflows] Improve on unavailable shard exception flakiness in c…

…ypress (elastic#197864)

## Summary

The cypress task `cy.task('indexEndpointHosts')` sometimes throws
`no_shard_available_action_exception`, when transforms are stopped. This
looks like a temporary issue, and in other tests it is simply retried.

This PR adds the retry logic for this type of error, and unskips some
tests.
