V5 Grid System docs issues

Created by: kohheepeace

I've found docs issue at https://getbootstrap.com/docs/5.0/layout/grid/#example

📌 Issue

Does col-sm creates three equal-width columns across all devices and viewports?

📌 Issue example

The below image is layout of iPhone 6 plus. It doesn't create 3 columns.

📌 Docs at v4.6

I think docs at v4.6 is correct. https://getbootstrap.com/docs/4.6/layout/grid/#how-it-works

The above example creates three equal-width columns on small, medium, large, and extra large devices using our predefined grid classes. Those columns are centered in the page with the parent .container.

PR

If this is an issue that needs to be fixed, I'd like to send a PR.

Thanks !
