feat(astro): Always add BrowserTracing (#13244)

The bundler-plugins still refer to the option as
`excludePerformanceMonitoring`
([here](https://github.com/getsentry/sentry-javascript-bundler-plugins/blob/main/packages/bundler-plugin-core/src/types.ts#L260)),
but this is going to be renamed to `excludeTracing`, so I already used
the new naming as discussed with @Lms24 and @mydea.

closes #13013
