[Humble] Remove --with-new-pkgs when upgrading packages in CI

[sea-bass]

Description

This is my next theory as to why the humble-ci job continues to fail in #3080 even though there have been new packages released.

Curious if anyone has perspective on why this was added in the first place, and whether it's undesired to change it.

Checklist

• Required by CI: Code is auto formatted using clang-format
• Extend the tutorials / documentation reference
• Document API changes relevant to the user in the MIGRATION.md notes
• Create tests, which fail without this PR reference
• Include a screenshot if changing a GUI
• While waiting for someone to review your request, please help review another open pull request to support the maintainers

[mergify]

Please target the main branch for development, we will backport the changes to humble for you if approved and if they don't break API.
