Test_TC_CGEN_2_1.yaml BasicCommissioningInfo should not use specific hardcoded values

Problem

After #19582 this xml looks like

          value:
              {
                  FailSafeExpiryLengthSeconds: 60,
                  MaxCumulativeFailsafeSeconds: 900,
              }

While these are the default values they are not the required values and cert testing should just make sure that these fields are populated with some value greater than 0

@kowsisoundhar12 please take a look?

@raju-apple can you make sure the test case steps are also updated, it sounds like we need to fix both the YAML and maybe the test steps.

Currently looks like we don't have a way to check the range within a struct value in yaml (#17997) , But for now we can put up a manual user prompt just for this step for the user to validate its within the range and not checking a specific value. @kvikrambhat Can you please put the PR for this modified script once its up please ?

Solved in #19672. Closing.
