Mute RemoteIndexPrimaryRelocationIT (opensearch-project#12389)

When this test fails, it takes [15 minutes to timeout][1]. There are
many examples like this. While it generally succeeds after a retry or
two, I think it is better to mute this test rather than observe regular
failures that extend build times.
