Add upgrade tests

[vladjdk]

Add tests that test for upgradeability between the previous version and current version of Gaia

Hi team,

I'd love to work on making tests more verbose as described here. I've successfully enhanced telemetry tests and would like to apply the same clarity improvements across other test suites.

Please assign this issue to me if needed. Thanks!

@vladjdk can you provide more details on this issue~ I thought interchain-test workflow already tests this flow
