Provide an updated 18F branded Guide template for Federalist

[cmajel]

There are a number of 18F guides in existence with divergent styles.

Examples:

• https://18f.gsa.gov/guides/
• https://eng-hiring.18f.gov
• https://before-you-ship.18f.gov/
• https://federalist-proxy.app.cloud.gov/site/18f/ux-guide/

One upcoming project where an 18F guide template would be used is for an open-source Guide to Hiring.

To do:

• [ ] Define what is an 18F "guide"

• [ ] Find the current home of the 18F guides template and its maintainer Candidates include:

• https://github.com/18F/guides

• https://github.com/18F/guides-template

• https://federalist-proxy.app.cloud.gov/site/18f/ux-guide/

• [ ] Audit existing guides to find patterns

• [ ] Propose an 18F branded guide template

• [ ] Implement

• [ ] Update past guides

Based on brand survey, we're going to wrap up this research and move to the backlog, and move up slide work.

Need to decide if we need an 18F version of the uswds-jekyll theme, and possibly use the one that @ryanhofdotgov created
