[Functionality] Clarify Deed/Legal code labeling, relationship, and placement on `license-page` contexts

## Problem
Presently the language of "deed" and "legal code" is output as part of the title styling of the page, and as such causes confusion as visitors may believe that they are part of the license title itself.

So rather than: `CC BY-NC-ND 4.0`

Individuals might believe the title is instead: `CC BY-NC-ND 4.0 DEED` or `CC BY-NC-ND 4.0 LEGAL CODE`.

## Description
Current pages:
* `deed:` https://creativecommons.org/licenses/by-nc-nd/4.0/deed.en, uses `walkthrough-page` context
* `license:` https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode.en, uses `default-page` context

Legacy versions:

* `deed:` https://web.archive.org/web/20230726193257/https://creativecommons.org/licenses/by-nc-nd/4.0/deed.en
* `license:` https://web.archive.org/web/20230723170747/https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode.en

## Alternatives
As `deed` and `legalcode` are descriptor "meta info" they should instead be placed elsewhere, and styled differently from the title itself. The previous design did a better job of creating this delineation.

## Additional context

The translations strings may present a challenge in trying to create a solution here.

To resolve this item, a working current state context for the `deed` and `legalcode` license-page contexts needs to exist to work from. That work is tracked here:
* #64

## Implementation
