Config strings are messy AF

[SallyMcGrath]

Describe the bug

In hugo.toml there's a load of random strings, like root, api, org, main_org_name because they've just grown up over time as we have discovered more and more string manipulation requirements

What is wrong with this content?

This is unfriendly lore for new users.

How could this be fixed?

Instead let's have a clearer taxonomy, something like

gitHubPrefix = 'https://github.com/"
gitHubAPI = "https://api.github.com/repos/"
gitHubOrg = "CodeYourFuture"
gitHubRootRepo = "curriculum"
gitHubPD = "CYF-PD" ??

And then go round and update all the calls in the regexes
