Copying first page of deploy guide to index.markdown

This simplifies the URL structure, so readers can go to /guides/deployment_guide and find content without knowing a specific page name.

Concurrent with this change, I'm submitting a pull request to have the first page 301'd to index.html. Once that redirect is in place and verified working, we can remove the original first page.

(#14704) Capitalized bare words are not strings

Clarify that bare words must start with a lower case letter in order to be
interpreted as strings. Bare words beginning with capital letters are
interpreted by the parser as resource references.
(#14301) Selectors cannot return hash literals

Selectors can return any `rvalue` as defined by the grammer. Hash literals fall
under the category of `expressions` and are rejected by the parser when used as
the return value of a selector.
