Un-skip migration batch size test

[mshustov]

I had to skip a SO migration integration test
b88c94c
due to a bug in Elasticsearch elastic/elasticsearch#79684

Un-skip the test when either the bug is fixed in Elasticsearch or elasticsearch-js implements a workaround.

Also affects the currently skipped test "resolves left request_entity_too_large_exception when the payload is too large" https://github.com/elastic/kibana/blob/master/src/core/server/saved_objects/migrationsv2/actions/integration_tests/actions.test.ts#L1542

test fixtures must be updated. after the root cause was resolved, the test fails with

This one is fixed by #119791

[pgayvallet]

test fixtures must be updated

This is caused by the presence of xpack types in the dataset. Changing oss: true to oss: false such as done here

kibana/src/core/server/saved_objects/migrations/integration_tests/7_13_0_failed_action_tasks.test.ts

Lines 137 to 139 in 6730b4b

	{
	oss: false,
	}

should do the trick

[mshustov]

@pgayvallet I agree, especially in the light of the necessity to remove oss: false from the integration tests.
