ci: route Swashbuckle (Swagger) Renovate updates to Platform

[amorask-bitwarden]

🎟️ Tracking

Follows Renovate PR #7774 ([deps] Billing: Update swashbuckle-aspnetcore monorepo to v10.2.3) and team discussion: Swagger
tooling is out of Billing's scope, and Platform will own it. No Jira ticket.

📔 Objective

PR #7774 was tagged [deps] Billing: because Swashbuckle.AspNetCore and
Swashbuckle.AspNetCore.SwaggerGen were listed under the "Billing owned
dependencies" rule in .github/renovate.json5.

This moves both packages to the "Platform owned dependencies" rule so future
updates route to team-platform-dev with a [deps] Platform: prefix. Only
ownership/routing changes — the packages are added solely to the team-ownership
rule (not the dashboard-approval rule), so PR-vs-dashboard update behavior is
unchanged.

Once merged, #7774 can be closed and regenerated from the Dependency Dashboard
so it re-routes to Platform.

Overall Assessment: APPROVE

This PR moves Swashbuckle.AspNetCore and Swashbuckle.AspNetCore.SwaggerGen from the "Billing owned dependencies" rule to the "Platform owned dependencies" rule in .github/renovate.json5, so future Renovate updates route to team-platform-dev with a [deps] Platform: commit prefix. The move is clean — both packages are removed from the Billing list and added to the Platform list with no duplication, and alphabetical ordering after Quartz is preserved. Neither package appears in the dashboard-approval rule (lines 226-240), so PR-vs-dashboard update behavior is unchanged as the description states. This is a routing-only config change — no dependency versions are added, removed, or bumped, so no security, correctness, or breaking-change concerns apply.
