[Icons] `<twig:UX:icon .../>` casing issue

[kbond]

ux.symfony.com/icons shows <twig:ux:icon .../> (lowercase UX). Considering the way we hijack rendering the component via an event, can we make case insensitive? I admit, uppercasing UX is a bit of a pain when writing manually.

We can! ...

Lowercase would just be "supported" or we make it the "official" case ?

We should use the same as much as possible, as i'm not sure of the implications in term of caching, opcode, etc.. :|

Yes, we should definitely be consistent in docs/code, and of course, projects should be consistent in their usage.

I'm not sure on the official case... I think I'm leaning towards <twig:ux:icon .../> (lowercase).
