Changes:
* Swaps the `dev` admonitions for `experimental` admonitions
* Removes `ifdef` statements preventing the docs from appearing in
released branches
Adds a concise list of EQL advantages, based on the "EQL Advantages"
section in the [EQL for the masses][0] blog post.
The intent is to inform users how EQL could benefit at a high level.

Adds documentation for the EQL `substring` function.
Supporting changes:
* Creates a new "EQL function reference" page
