• Bump @backstage/cli to version 0.30.0 in various packages.
• Update @backstage/plugin-kubernetes and related plugins to their latest versions.
• Upgrade devDependencies including eslint, prettier, and @playwright/test.
• Adjust package versions for @backstage/plugin-scaffolder-backend and @backstage/plugin-search-backend.
• Add new dependencies for json-schema-ref-parser and swagger-parser in yarn.lock.

These updates enhance compatibility and introduce new features while ensuring stability across the project.
