"You have set `optimizeDeps.esbuildOptions`…" error despite not setting it (or...?)

[wojtekmaj]

Describe the bug

I migrated my Vite 6.3.5 config to rolldown-vite to try it out. After what I thought would be a set of minimal changes, I was met with:

You have set `optimizeDeps.esbuildOptions` but this options is now deprecated. Vite now uses Rolldown to optimize the dependencies. Please use `optimizeDeps.rollupOptions` instead.

It took me quite a long time to figure out, that it's not me using said option; in fact, it's @vitejs/plugin-react. It would be very helpful to include the name of the plugin causing issues in the warning message itself.

Detecting which plugin set the option is a bit difficult. So for now I made a PR that changes the message to mention that a plugin may set the option (#209).
