Clean up prerelease when PR is completed

[MariusStorhaug]

Description

Should prereleases be garbage collected when the module is published in full version?

[jontreynes]

this can be updated here https://github.com/Azure/ResourceModules/blob/main/.github/actions/templates/publishModule/action.yml

and here https://github.com/Azure/ResourceModules/blob/main/.azuredevops/pipelineTemplates/jobs.publishModule.yml

As per the description - this issue is about clarifying whether to do it or not - not to implemented right way. Moving back to 'needs triage'

[rahalan]

Should be added as additional feature in the publish pipeline. It should also have a flag to turn the feature off.

[AlexanderSehr]

I'm a bit unsure about 'how' this should be implemented. Let's we introduce a flag in the settings - what should it effectively do? Upon running the publish, should it removal all versions with a '-prerelease' suffix? If so, what if there are different ones by different people? Maybe they still use the prerelease version. Etc.
