Update Pester conditions to run always

[AlexanderSehr]

Currently, the Pester test tasks are run in sequence & if one fails, the later are not executed properly.

Hence, we must update the conditions accordingly:

• The Pester task should always run and if it fails, the Pester-Publish tasks should still run
• The API task should always run and if it fails, the Api-Publish tasks should still run

The issue happens in GitHub - but ADO should be checked too.
