Fix Silero VAD Static Paths

Currently in [next.config.js](https://github.com/bephrem1/vocalized.dev/blob/main/next.config.js#L31) we place static files for the [VAD package](https://github.com/ricky0123/vad) under `static/chunks/pages`. This was due to an import error during runtime where the `ricky0123/vad` package code would only look at that root path for static files (there's no config to have the library looks to a different path). So I set the files to be copied over there.

Ideally we pick & choose the actual place we want these files to be in the build via some param (which I think they may expose), instead of hacking things to align.

Everything works though (locally & in prod), but sort of hacked. Need to put more attention back on this issue to prevent weird future breakages.
