Reorg the get/create Resource pages

[bep]

I tested the search now checking if I could find the "get remote resource" documentation:

And that's not great.

We can certainly also tweak the Algolia setup (wherever that is ...), but I suggest we do a reorg of this into fewer entities, e.g.:

# Get or Create a Resource

## Get Local Resource

## Get Remote Resource

## Create Resource from String

## Create Resource from Template

Etc...
....

This is a core Hugo concept that needs a more clear placement/disposition.

@bep I was planning to attack this once https://github.com/gohugoio/hugo/pull/9063 was implemented. Having identical calls regardless of resource type would make it a bit easier to explain, but it is certainly not a show stopper.

Ah, OK, I had a PR for that, but I ... forgot it for some odd reason.

This will be addressed in https://github.com/gohugoio/hugoDocs/issues/2307
