feat(nuxt): Improve logs about adding Node option 'import' (getsentry…

…#13726)

Adding the node option can be a confusing step. This adds a log output
which already includes the correct file path to add. It looks like this:
```
[Sentry] Using your sentry.server.config.ts file for the server-side Sentry configuration. 
Make sure to add the Node option import to the Node command where you deploy and/or run your application. 
This preloads the Sentry configuration at server startup. You can do this via a 
command-line flag (node --import ./.output/server/sentry.server.config.mjs [...]) or via 
an environment variable (NODE_OPTIONS='--import ./.output/server/sentry.server.config.mjs' node [...]).
```
