Document existence of site global function

[earthboundkid]

gohugoio/hugo#5470 is great, but AFAICT it's not documented anywhere. I was writing a partial and thinking "I thought there was some way of getting a global site function?" and I only found it by just experimenting and trying {{ site }}. Maybe I saw it in a Regis blog post at some point or something. Anyway, it should be in the list of Functions, if nothing else.

It is, and I agree that we need to improve this, but that is anohter issue.
