message: meta: Update 6.17.0 CHANGELOG
diff: This release contains several internal refactors that help reduce the bundle size of the SDK and help prep for our [upcoming major release](https://github.com/getsentry/sentry-javascript/issues/4240). There are no breaking changes in this patch unless you are using our internal `Dsn` class, which has been removed. We also deprecated a few of our typescript enums and our internal `API` class. We've detailed in our [migration documentation](./MIGRATION.md#upgrading-from-6.x-to-6.17.0) how to update your sdk usage if you are using any of these in your code.
