Add TypeDoc example, improve navbar

[srmagura]

• Closes Add rendered example folder to typedoc.org typedoc#1759.
• Closes Website: Improve nav link placement on mobile devices typedoc#1767.
• Closes Fix nightly publish script on typedoc-site typedoc#1757.
• Simplify the publish workflow.
• Hide the table of contents on mobile since it was at the bottom of the document and did not have proper margin/padding.
• Fix the Gulp plugin table overflowing the body on mobile.

The "Guides" and "Changelog" nav links were consolidated under the "Docs" link.

• The URL of the Changelog page changed as a result.
• I did NOT change the URLs from /guides/whatever to /docs/whatever to avoid breaking links.

Sorry for so many changes in one PR, this just seemed like the easiest way to do it.

TODO

1. Gerrit: Merge Tweak the example's typedoc.json typedoc#1775.
2. Sam: Verify that publish workflow passes now.
3. Gerrit: Merge this PR.

Looks reasonable, thanks! I guess nodes will always start with a clean checkout? Seems like a good thing...

You're welcome. I'm not 100% sure what you mean, but if you're referring to this change,

- test -f typedoc || git clone [email protected]:TypeStrong/typedoc.git
+ git clone https://github.com/TypeStrong/typedoc.git

the test is unnecessary because each job in a workflow runs on a fresh VM.
