these test fixtures belong to main scope, and there is a backlog task eliminate "testRuntimeMigration" (#16307).

After moving to main scope checkerframework errors seen. This are test fixtures so fix is of lower priority and deferred.

Change on github action won't be effective in PR so the ElasticSearch IO Direct would fail due to target not found.

Test on upstream branch passed: https://github.com/apache/beam/actions/runs/9573608254/job/26395346618

@Abacn can you please investigate the failing check[1] that's reporting elasticsearch-5 as not being found in the project?

Agreed that these versions are EOL, but we should likely include release notes. It might also be preferred to formally deprecate for 1 release version as well.

test passed, explained here: #31639 (comment)

we didn't actually test elasticsearch-5 : #31640 , In other word Beam has been exercising elasticsearch 7 and 8 tests only for long so there is not actual change on support status.
