When you open Mesh page on the OSSM3 + Kiali setup in the downstream pipeline, the graph contains one more node because Tempo is in a different namespace, and the test fails on

Unexpected number of infora nodes: expected 10 to be equal 9

Update the test to take this into account.

• Simple way, we can just tag it with some tag, e.g. `@skip-downstream` and we can skip that test in the downstream pipeline + create the same test with tempo and add tag e.g. `@downstream-only`
• Refactor that test to be able to expect both, 9 or 10 nodes in the graph according to something

See Mesh pages on both setups
