skip deploy job when package version has not been increased

[baywet]

All the packages workflows currently have a similar issue for the deploy job: if the version hasn't been bumped, it will fail as conflicting during the deployment phase.
The list of workflows includes all workflows starting with abstractions-, authentication-, serialization- and http-.

Here is what we need:

• 3 new powershell scripts in the "scripts" folder.
• each script will take a path, a package name, and a feed url as mandatory parameters.
• each script will be dedicated to one package ecosystem (npm, nuget, maven).
• each script will get the latest version of the package on the feed for the given package name
• each script will get the version of the package in the package path that's been provided
• each script will compare the two versions and set a workflow variable indicating whether the package versions on the feed and in the package file are identical or not
• workflows deploy job will be updated to call that the corresponding version check script with corresponding parameters
• subsequent steps need a condition to execute only if the value has changed

@wcontayon do you feel like you could take on this one? are the instructions I put together clear enough?

@baywet, I can try a PR on it. It'll improve my scripting knowledge 🙂 🙂

Thanks! Assigning to you. Don't hesitate if you have questions.

Closing this as we're moving the kiota packages for each language to their own repo and it will be the responsibility of the dedicated repo to handle that depending on the deployment workflow.
