[Functionality] add localized `license-page` context(s)

[possumbilities]

Problem

The license pages are not included as contexts within index-prototype, and cannot be tested against reliably.

Description

At current the license pages for the legal code and the deed pages are stylized, but are variants of, existing contexts with hyper localized stylings of their own.

html:

• 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

css:

• base.css: https://github.com/creativecommons/cc-legal-tools-app/blob/3bc446c0343733506f8cd54ca1173654b8cdfac6/cc_legal_tools/static/cc-legal-tools/base.css
• deed.css: https://github.com/creativecommons/cc-legal-tools-app/blob/3bc446c0343733506f8cd54ca1173654b8cdfac6/cc_legal_tools/static/cc-legal-tools/deed.css
• legalcode.css: https://github.com/creativecommons/cc-legal-tools-app/blob/3bc446c0343733506f8cd54ca1173654b8cdfac6/cc_legal_tools/static/cc-legal-tools/legalcode.css

Despite the use of existing contexts, there are several sub-elements and stylings which do not pull from vocabulary core at this time. Neither page exists as a context within this repository, but should. For now, work should start here, and after being finalized it might be possible to generalize it back to a vocabulary core context, for now, it's existence as production markup+styling without a corresponding index-prototype context is out of process, and difficult to both build for and test.

This should be either:

• one generalized local context, such as: license-page
• two similar, but distinct local contexts: deed-page, legalcode-page

Alternatives

There is also a case that this should be a possibility within a robust enough walkthrough-page context, but it does not fully exist yet.

Implementation

• I would be interested in implementing this feature.
