fix: Added baseTime parameter overwrite to CI (#2740)

## Description

Many of our test cases implement the parameter `param baseTime string =
utcNow('u')` to generate unique names.
While a good idea in theory, it has the flaw that also each retry will
lead to a new value which can cause re-runs to fail if for example a key
vault referenced for CMK suddenly changes.
The proposed solution is to set the value once per pipeline run in the
workflow and hence overwrite the default value of each template IF the
template contains the `baseTime` parameter.
