Remove all docs now that they've been deprecated

Docs Update Description

We have a beautiful new docs site now, so it is time to retire the old one.

We can remove the docs subdir as well as associated CI workflows, nox sessions, etc.

@conceptualshark are you ok with this change?

[conceptualshark]

I am! Suchi is going to (or has) put in a a banner message that we've moved the docs, so I think we should leave the build in place for a sprint or two to make sure that's clear?

[ThomasLaPiana]

we'll need to update any code references to it, can we also directly do a redirect from the current url to the new docs site?

[conceptualshark]

I believe @suchiroll looked into it and a redirect wasn't possible (so we went with a banner) - let me confirm a process/timeline for when we want to remove everything, and I can get back to you!

[ThomasLaPiana]

@conceptualshark ok, so let me clarify the current situation a bit:

1. We have a new docs site (docs.ethyca.com/fides/overview)
2. We have an old docs site (ethyca.github.io/fides) that we are pointing to in some places

I have a few questions:

1. What is pointing to the old docs site?
2. What is pointing to the old docs site that we can't update?
3. How long do you propose keeping the old site around for?
4. How do we handle docs updates during this transition period?

Hey @ThomasLaPiana — do we have the knowledge in the eng. team at this time to keep the new docs up to date? If not, I'll add a ticket to action that.

[ThomasLaPiana]

@seanpreston nope, I don't think the new docs processes have been communicated

Closed this via refactoring the docs
