Add CHANGELOG enforcement to release process (#413)

* Add CHANGELOG enforcement to release process

* Test: validate test failure if no changelog entry present

* Disable release and use an echo instead. Revert before publishing

* add entry for 1.0.0-dev.1 with no release date (expect failure)

* Add date but no content (expect failure)

* adding content, expect validation to pass

* Revert changes used for testing

* Revert "Test: validate test failure if no changelog entry present"

This reverts commit a702f0053bb60839ff722a5656d90c75568b7ca9.

* Use Powershell@2 task instead of pwsh for better debugging

* Update version and disable actual release tagging for validation of Powershell@2 task changes

* Revert "Update version and disable actual release tagging for validation of Powershell@2 task changes"

This reverts commit 53bfd04746cc9d0060fa8dd29b4acfcacd015add.
