fix(framework): Specify zod-to-json-schema as a dependency

[rifont]

What changed? Why was the change needed?

• Use runtime import for zod-to-json-schema in @novu/framework
  • Without a runtime import, build tools would attempt to import zod-to-json-schema at build-time which results in build failure when the optional peer dependency is not installed. This forces @novu/framework consumers to always install zod-to-json-schema even if they don't use zod

Screenshots

Before - error shown at build time:

Module not found: Can't resolve 'zod-to-json-schema'

Verifying that @novu/framework can be used without Zod now

import { workflow } from '@novu/framework';
