feat(hono): Emit warning if `@sentry/node` was imported instead of `@sentry/hono/node` (#21240)

The Hono Node setup requires a separate instrumentation file with the
`Sentry.init()` call. It's important that `init` is imported from the
Hono SDK and not Node. As this could easily be overlooked, but is very
important for the correct setup, this warning is added.
