Fix release tests for SemanticMatchTestCase

[ioanatia]

#119041
#119042

verified the fix by running:

 ./gradlew ":x-pack:plugin:esql:qa:server:multi-node:javaRestTest" --tests "org.elasticsearch.xpack.esql.qa.multi_node.SemanticMatchIT.*" -Dtests.seed=9E0A907FC60B1BDE -Dbuild.snapshot=false -Dtests.jvm.argline="-Dbuild.snapshot=false" -Dlicense.key=x-pack/license-tools/src/test/resources/public.key

same for single node tests.

example of a build scan failure: https://gradle-enterprise.elastic.co/s/dzxl5mrinyrqq

moving the assumption that checks the esql capability to the test methods fixes the issue.

@elasticmachine merge upstream

LGTM !

I think you can use BeforeClass to check assumptions in one place - I think I used that for other tests, although they were not ESRestTestCases

@original-brownbear as we discussed I am muting this test for main - it was already muted on 8.x.
