Remove experimental for modularizeImports from docs and example (#44311)

When `modularizeImports` was moved out of experiimental [on this PR](#44240), `docs` and `examples` were not updated.

- Update `modularize-imports` example by removing `experimental` from `next.config.js`, as it's currently failing when deployed
- For docs: https://nextjs.org/docs/advanced-features/compiler#modularize-imports
  - Move `Modularize Imports` section outside of `Experimental Features` section 
  - Remove `experimental` from code snippets
  - Added to version history, just like when SWC Minifier became stable.

## Documentation / Examples

- [x] Make sure the linting passes by running `pnpm build && pnpm lint`
- [x] The "examples guidelines" are followed from [our contributing doc](https://github.com/vercel/next.js/blob/canary/contributing/examples/adding-examples.md)
