code examples: Removing text-shadow on the AngularJS bits will improve readability

I'm submitting a...

[ ] Regression (a behavior that used to work and stopped working in a new release)
[ ] Bug report  
[ ] Feature request
[x ] Documentation issue or request
[ ] Support request => Please do not submit support request here, instead see https://github.com/angular/angular/blob/master/CONTRIBUTING.md#question

Current behavior

On https://angularjs.org, the styling on the AngularJS bits (tags, attributes, placeholders) in the code examples include a white colored text-shadow on a light blue background. This makes text difficult to read from 2-3ft (for example, a desktop monitor).

Expected behavior

The text doesn't need the white text-shadow. The light blue background is enough to identify it as AngularJS related.

Minimal reproduction of the problem with instructions

1. Visit https://angularjs.org
2. Scroll down to one of the code examples
   

What is the motivation / use case for changing the behavior?

Changing will improve usability and possibly accessibility.

FWIW, neither looks very readable to me 😁
Maybe making the background lighter might help.

Apparently the fix needs to be done at https://github.com/angular/angularjs.org

I re-moved the moved issue and closed my PR 😕 🙈
