[docs] Show details about GitHub PAT for package management

[rfay]

The Issue

I couldn't figure out where the (expired) package management PAT was used. But it was already documented.

How This PR Solves The Issue

Give more context about it.

Is this the formatting you intended, @rfay?

I’m usually not a fan of “see X” style links that could use more contextual anchor text, but escaping the link itself seems downright reader-hostile since they’ll have to copy and paste it.

I think it actually is the right formatting. Hard to work with though. The URL to the PAT can't pass docs check because it's not a public URL, that's why it's back-quoted. The name of the token is "Package management token see ... url"

So very awkward, but probably what I was trying to accomplish.

Definitely reader-hostile. Very, very small audience.

Oh I see. Awkward but intentional. No more questions from me, then!
