Proposed changes

Modifies the release workflows to make it easier to configure and hopefully easier to troubleshot if needed.

Release Agent workflow

• When drafting a release, add a warning to not squash commits when merging back the release branch
• input options have been re-arranged to be a little clearer and add some defaults to the descriptions.

Publish Release Assets workflow

Gathers the signed release packages from our official package repository, and publishes to GitHub release and Azure blob storage (if requested).

• Move the package preparation logic into the scripts/packages/package-check.sh script.

package-check.sh

• Modify configuration of download paths to be easier to add/remove paths when new OS versions are added/removed.
