multicluster: Fix metadata prefix matching (linkerd#7825)

When formatting event metadata, the method `formatMetadata` checks if a given string in the metadata map contains a given prefix. However it does this using `strings.Contains` rather than `strings.HasPrefix`, which will return true if the given prefix string is located anywhere in the target string to search.
