Align styling of inline code snippets

[formgeist]

Noticed that the styling we use for inline code snippets don't exactly follow the same style as on elastic.co, so this becomes evident when using the setup instructions in Kibana, that the styling is quite different.

Example of the current EUI styling

Example of the elastic.co styling

Wondering if there's consensus to align the two for consistency (and brand), or at least create another style prop for having a highlighted version which could be used for i.e. setup instructions, so there's an option for the devs to use which they prefer.

Thoughts?

We chatted this up in our design meeting. Decision was that EuiCode should...

• Use the full font size.
• Maybe add some more padding horizontally.
• Color was fine.

I can take this on.

Our side of this was merged.
