[CI] RestGetSnapshotsIT testLargeChunkedResponses failing

[DaveCTurner]

Similar to my comment at #89906 (comment) - we shouldn't need to make such a big state to test this, let's assert that we're emitting chunks more cheaply.

Build scan:
https://gradle-enterprise.elastic.co/s/chaqkujb74bqi/tests/:qa:smoke-test-http:javaRestTest/org.elasticsearch.http.snapshots.RestGetSnapshotsIT/testLargeChunkedResponses

Reproduction line:
./gradlew ':qa:smoke-test-http:javaRestTest' --tests "org.elasticsearch.http.snapshots.RestGetSnapshotsIT.testLargeChunkedResponses" -Dtests.seed=5B081F1C9FA0F56A -Dtests.locale=ar-LB -Dtests.timezone=Europe/Vilnius -Druntime.java=17

Applicable branches:
main

Reproduces locally?:

I agree, I'll remove the test, we already have a specific test about the chunk count.
