[CI] EqlActionIT test failing reproducibly

Just got a whole batch of failures for EqlActionIT. Example:

org.elasticsearch.xpack.eql.action.EqlActionIT > test {1.test} FAILED
    java.lang.AssertionError: no proxy found for action: org.elasticsearch.xpack.eql.action.EqlSearchAction@84757f79

So far all the failures are in the 7.x branch. The example above reproduces for me locally.

Since this reproduces, and we have over a dozen failures already I've gone ahead and muted this in 7.x with 025352f.

The issue was addressed with the backport PR #52725.
Will open another PR to unmute the test.
