adds kurtosis-assertoor to ci

[sudeepdino008]

kurtosis assertoor tests in ci

decision points:

• since the job takes about 45 minutes to run, I decided not to run it on every PR, but rather we run it every 12 hours at 2AM/PM UTC.
• all tests are present in https://github.com/ethpandaops/assertoor-test/tree/master/assertoor-tests. This ci runs these tests.
• test is for ubuntu only; not for mac or windows.

Many tests are failing; specially the validator related ones. Tracked separately - #11590
