[RR7] Add vite plugin for updating sentry options in vite config

### Description

Currently the user needs to pass the sentry config to both the vite config AND our vite plugin.
We could probably make this prettier by just adding a new plugin within our existing vite plugin that updates the global vite config with our sentry options (so that they are available for our buildEnd hook)
