Carbon: Theme configurations need updating with variable-2 and variable-3 options

Syntax highlighting with php seems broken

Whatever the theme I choose, syntax highlighting for PHP seems broken.

This is what it should show (as seen on codemirror demo page). It shows two different colors for variables and methods (blue and black):

But this is what I get with "dracula" theme on carbon. It only shows one color (white) for both variables and methods:

This is an extract from theme's css, we should get two different colors:

.cm-s-dracula span.cm-variable { color: #50fa7b; }
.cm-s-dracula span.cm-variable-2 { color: white; }

but while inspecting I get something different:

Here is a live example, but I noticed it on most php snippets I saw on twitter: https://carbon.now.sh/1HBRbot05AIFiezO6H2n

Thanks for posting this. Just pushed this PR (https://github.com/carbon-app/carbon/pull/988) that fixes the underlying issue, and the configuration for Dracula, but it does not fix it for other themes.

It would be _amazing_ if someone went through and set the variable-2 and variable-3 configs correctly for the other themes.

If no one else takes it, I will try and get to it eventually 👍
