Renovate keeps creating dotnet monorepo updates

[askpt]

Description

Renovate keeps reopening PR #438, which appears to be marked as "immortal." This behaviour suggests that there might be a configuration issue in our Renovate setup.
One of the suggestions is to set the updates to be open only on approval: https://docs.renovatebot.com/key-concepts/pull-requests/#immortal-prs.

Tasks

1. Investigate why PR chore(deps): update dotnet monorepo #438 is marked as "immortal."
2. Review Renovate's configuration for the repository to identify potential improvements.
3. Ensure that unnecessary "immortal" PRs are not repeatedly created by Renovate.

Expected Outcome

• Understand the root cause of this behaviour.
• Update Renovate configuration to prevent similar issues in the future.
