doc: cleanup doc on need of Developer Account to obtain macOS SDK

Browse source 
The explicit statement that an Apple Developer Account is required in
order to obtain the SDK is buried within the "Deterministic macOS DMG
Notes" section. It should be the first thing mentioned under the "SDK
Extraction" section. The reason to do this is to set expectations of
what is required before starting any steps or clicking on links.

This fixes the issue by doing just that; moving this information to the
"SDK Extraction" section. Now that the information is moved, this also
deletes unnecessary SDK related notes from the "Deterministic macOS DMG
Notes" section. It is not necessary to explain under what sub-directory
'most' of the important files are inside of the 'Xcode.app'.

### Step 1: Obtaining `Xcode.app`
A free Apple Developer Account is required to proceed.
Our current macOS SDK
(`Xcode-12.2-12B45b-extracted-SDK-with-libcxx-headers.tar.gz`) can be
extracted from
[Xcode_12.2.xip](https://download.developer.apple.com/Developer_Tools/Xcode_12.2/Xcode_12.2.xip).
Alternatively, after logging in to your account go to 'Downloads', then 'More'
and look for [`Xcode_12.2`](https://download.developer.apple.com/Developer_Tools/Xcode_12.2/Xcode_12.2.xip).
and search for [`Xcode_12.2`](https://developer.apple.com/download/all/?q=Xcode%2012.2).
An Apple ID and cookies enabled for the hostname are needed to download this.

To complicate things further, all builds must target an Apple SDK. These SDKs are free to
download, but not redistributable. To obtain it, register for an Apple Developer Account,
then download [Xcode_12.1](https://download.developer.apple.com/Developer_Tools/Xcode_12.1/Xcode_12.1.xip).

This file is many gigabytes in size, but most (but not all) of what we need is

The Guix process builds 2 sets of files: Linux tools, then Apple binaries which are
created using these tools. The build process has been designed to avoid including the
SDK's files in Guix's outputs. All interim tarballs are fully deterministic and may be freely
redistributed.
