[Docs] Column order classes missing Sass variable name

Describe the issue

The docs say at https://getbootstrap.com/docs/5.3/layout/columns/#order-classes:

Order classes

Use .order- classes for controlling the visual order of your content. These classes are responsive, so you can set the order by breakpoint (e.g., .order-1.order-md-2). Includes support for 1 through 5 across all six grid tiers. If you need more .order-* classes, you can modify the default number via Sass variable.

It is not clear which Sass variable needs to be modified. Adding the var name would be helpful.

Reduced test cases

Not applicable to docs, I guess?

Thanks for opening this issue @TobiGr

I think that the sentence is even misleading, as there's not really a Sass variable to modify. I mean, there is, but it's the content of $utilities that must be updated, because the responsive order utility is built like this:
