Somehow this test isn't muted in release tests: https://buildkite.com/elastic/elasticsearch-periodic/builds/4386#0192809b-20f3-4626-8958-cccf7ee480a7/6-2132

Looks like testGet was updated to testCRUD in this change. Looking back at the assertion that was failing, it looks related to the total number of endpoints we expect to exist (see here). testCRUD is not muted and has not been failing so it seems the updates we've made should have accounted for this. I'll go ahead and remove this from the muted tests.

Removed from muted tests in main. Looks like this is not muted in 8.x. Closing now.
