Resloves: #41820
## Summary
- Adds `1.5rem` vertical margin to the GitOps mode info banner on the
**Software > Add Software > Custom Packages** page
- Uses an instance-level `className` prop
(`software-custom-package__gitops-banner`) and a page-scoped SCSS rule,
following existing codebase patterns for instance-specific spacing
- Does **not** modify the shared `InfoBanner` component styles
## Changes
-
`frontend/pages/SoftwarePage/SoftwareAddPage/SoftwareCustomPackage/SoftwareCustomPackage.tsx`
— Added `className` prop to the GitOps `InfoBanner` instance
-
`frontend/pages/SoftwarePage/SoftwareAddPage/SoftwareCustomPackage/_styles.scss`
— Added `&__gitops-banner` rule with `margin: 1.5rem 0`
