I intentionally moved builtins at the beginning of the list.

@serhiy-storchaka What prompted you to move to the beginning? Perhaps we need a sentence or section break between them@hugovk

Builtins look special to me, and in some other places we list them separately from other modules. I thought that even if we list them in the common list with other modules, it is worth to move the builtins module to the beginning. But I may be wrong here -- in few last What's New files (3.13, 3.14) they are listed alphabetically in the list of modules.

Thanks for clarifying@serhiy-storchaka.@hugovk, do you want to offset built-ins from the rest of standard library modules?

In a way it's just another module in the docs, and I'd prefer alphabetical, but I don't mind too much.

If we're browsing a long list, it's easier to find alphabetically, and it'll be less likely for new edits to be added in arbitrary order if it begins with A instead of B.

cc@AA-Turner who edited the last two versions, any opinion?

I'm going to go ahead and merge this to unblock the PR. We can always create future iterations to improve the difference between builtins and the other libraries.
