Download installApps and installTestApps as part of "Download Project Dependencies"

[aholstrup1]

❔What, Why & How

Currently
Apps defined in the installApps and installTestApps settings can either refer to files in the file system or URLs to files. If a URL is defined, then the Runpipeline action will check that the URL is reachable and Run-ALPipeline (in BCContainerHelper) will download the apps.
installApps and installTestApps can also refer to local paths (either full paths to .app files, folders, paths with wildcards or even zip archives).

Proposed Change
We move the download of these apps to the "Download Project Dependencies" action. That way most dependencies should be downloaded to the runner before calling Run-ALPipeline. This action would still not resolve dependencies from NuGet. That's something we should add in the future.
For local paths, we will try to resolve the paths within AL-Go rather than relying on Run-ALPipeline to do it. That way this action should return a list of paths to .app files.

• Added functionality to DownloadProjectDependencies action to download app files from URLs in installApps/installTestApps settings
• Removed URL validation and secret resolution logic from RunPipeline action
• Updated RELEASENOTES.md to document the new behavior
