Extracted from the semver-compatible lockfile upgrade PR (commit 19831fd).

• Removes the mongodb6: npm:mongodb@^6.9.0 alias and the ['6.x driver', ...] row in packages/devtools-connect/src/connect.spec.ts.
• Plus the peer/optional range narrowing in packages/devtools-connect/package.json (commit d0641f8): mongodb ^6.9.0 || ^7.0.0 → ^7.5.0, kerberos → ^7.0.0, mongodb-client-encryption → ^7.2.1, mongodb-connection-string-url → ^7.0.2, @mongodb-js/oidc-plugin → ^2.2.0.
• These are breaking published-package changes (dropping driver 6 support for consumers) — definitely its own PR, and needs a major/breaking release note.
