feat: Improve changelog history display for stable-only repositories

[LbsLightX]

Feature description

Currently, the in-app changelog fetcher groups releases by showing all dev/pre-releases attached to the latest stable release. When a new stable version is released, the display resets to show only that single stable changelog.

• The Issue: If a repository only publishes stable releases (no dev/pre-releases), the app strictly displays one changelog.

Implement logic (or a user toggle) to display a brief history of the last 5 to 8 releases for repositories that exclusively push stable versions.

Motivation

Currently, the app forces users to leave the manager and visit GitHub just to see recent updates for repositories that only publish stable releases. By displaying the last few changelogs for these stable only repos, we can fix this UX gap, keep users inside the app, and provide a consistent viewing experience regardless of how a developer structures their releases.

• I have checked all open and closed feature requests and this is not a duplicate.
• I have chosen an appropriate title.
• The feature request is only related to Morphe (Manager).

The manager shows changelogs only for the missing version, i.e. if the user has skipped several stable versions, only these versions will be shown. This is expected behavior.

So, when you say 'skip several versions,' wdym? Is it that I fetch that particular repo for updates, do I need to participate in those versions for patching, or is it basically like seeing the changelog itself as a read message?
